2. SmartFlow principal areas and flexibility

SmartFlow is very useful for● sizing differential pressure devices from flow rate and pressure difference● flow rate and delivered energy calculation from orifice or nozzle diameter and

pressure difference● pressure difference calculation from flow rate and orifice or nozzle diameter

in power station and also open air or wherever. SmartFlow can be used for the most relevant fluids used in the industry and measured by differential pressure device (see 3.1) or other flow meter. The above mentioned calculations will be entirely done. The upper and lower limits defined in standards are permanently checked and indicated by message boxes in case of exceeding during calculation. Uncertainties belonging to calculated results can be also calculated by each computing modules. These uncertainties can be contain the uncertainties of input values (e. g. trans-ducers) and/or algorithm-uncertainties defined by relevant standards.SmartFlow can calculate also the total uncertainties of

● flowing fluid properties● measuring tube (uncertainty of flow rate, delivered energy etc.)

In case of crude oil or refined product SmartFlow can calculate the● mass flow from line volume flow measured by flow meter● stored mass of product from stored volume

SmartFlow can be used for flow computer verifications for both

● differential pressure device● other than differential pressure device

measurements. Flow computers can be also verified for● flow rate and energy flow● totalised flow volume and energy

2.1 Sizing of measuring tube with differential pressure device from flowrate and pressure difference

In the measuring tube with known diameter flows the fluid with known line pressure and temperature and maximal flowrate. From these SmartFlow can calculate the diameter of orifice plate or nozzle suitable for flowrate (and delivered energy) measuring by available differential pressure transducer or other differential pressure device.

During this calculation SmartFlow first calculates the physical properties of flowing fluid (from pressure, temperature and composition of fluid) than calculates the diameter of ori-fice plate or nozzle.This calculation can be made by ISO 5167 module, Calculation type is Diameter calcu-lation of orifice (nozzle) (see below):

Figure 1. SmartFlow – Selection of diameter calculation in ISO 5167 module

The further parameters are to set or type correctly. The maximal pressure difference be-longing to the maximal flow rate is to type by Maximum differential pressure parameter. It will define the sizing workpoint. The physical properties of flowing fluid will be calculated by Flowing fluid Dialog and the diameter from these results. (Parameter settings and us-ing of Flowing fluid Dialog see detailed in 3.1). The diameter calculation occurs by „Start calculation!” button. (When Show detailed inputs in the Settings menu is enabled, the „Start calculation!” button can be hit on the „Additional inputs | Calculation” tab.) –The use of parameters later will be supported by context sensitive help available by pressing F1 function key standing on the label or edit box (drop down) of the pending parameter (still under construction).

2.2 Flow rate and delivered energy calculation from diameter of orifice (nozzle) and pressure difference

In the measuring tube with known diameter flows the fluid with known line pressure and temperature. When the diameter of orifice or nozzle and the pressure dirrerence are known, from these SmartFlow calculates the flow rate and delivered energy.

During this calculation SmartFlow calculates first the physical properties of flowing fluid (from pressure, temperature and fluid composition) than calculates the flow rate. If neces-sary SmartFlow calculates the delivered energy (in case of either flowing fluid!).This calculation can be made by ISO 5167 module, Calculation type is Flow rate calcu-lation (see below). If delivered energy will be also calculated it can be set by Energy flow calculation drop down.

Figure 2. SmartFlow – Selection of flow rate calculation in ISO 5167 module

The further parameters are to set or type correctly. The pressure difference(s) belonging to the flow rate(s) is (are) to type by Maximum (and Minimum) differential pressure parameter. The physical properties of flowing fluid will be calculated by Flowing fluid Dia-log and flow (and energy) rate from these results. (Parameter settings and using of Flow-ing fluid Dialog see detailed in 3.1). The flow and energy rate calculation occurs by „Start calculation!” button. (When Show detailed inputs in the Settings menu is enabled, the „Start calculation!” button can be hit on the „Additional inputs | Calculation” tab.) –The use of parameters later will be supported by context sensitive help available by pressing F1 function key standing on the label or edit box (drop down) of the pending parameter (still under construction).

2.3 Calculation of pressure difference fromflow rate and diameter of orifice or nozzle

In the measuring tube with known diameter flows the fluid with known line pressure and temperature. When the diameter of orifice or nozzle and the flow rate are known, from these SmartFlow calculates the pressure dirrerence.

During this calculation SmartFlow first calculates the physical properties of flowing fluid (from pressure, temperature and composition of fluid) than calculates the pressure differ-ence.This calculation can be made by ISO 5167 module, Calculation type is Differential pressure (see below). SmartFlow can calculate also the pressure dirrerence to minimal flow rate, it can be set by Calc. of minimal differential pressure from drop down.

Figure 3. SmartFlow – Selection of pressure difference calculation in ISO 5167 module

The further parameters are to set or type correctly. The flow rate(s) belonging to the pres-sure difference(s) is (are) to type by Maximum... (and Minimum...) flow rate parameter. The physical properties of flowing fluid will be calculated by Flowing fluid Dialog and pressure difference(s) from these results. (Parameter settings and using of Flowing fluid Dialog see detailed in 3.1). The pressure difference calculation occurs by „Start calcula-tion!” button. (When Show detailed inputs in the Settings menu is enabled, the „Start calculation!” button can be hit on the „Additional inputs | Calculation” tab.) –The use of parameters later will be supported by context sensitive help available by pressing F1 func-tion key standing on the label or edit box (drop down) of the pending parameter (still un-der construction).

2.4 Flowing fluid properties calculation

SmartFlow calculates the flowing fluid properties during calculations described in 2.1...2.3 but the properties can be calculated also separately. In this case select the suit-able module from calculation type window (see in section 8. page 65.) The computing modules for flowing fluid calculations are

● IAPWS-IF97 thermodynamic properties of water and steam● ISO 6976 base density, Wobbe index and calorific value of natural gas● AGA8-DC92 (ISO 12213) density and compressibility factor of natural gas● AGA8 (SGERG) -G1 and -G2 compressibility factor of natural gas● GOST 30319 compressibility factor of natural gas● AGA NX19mod compressibility factor of natural gas● GOST 30319 natural gas dynamic viscosity and isentropic exponent● ISO 20765 thermodynamic properties of natural gas● PTZ natural gas density, volume and delivered energy● ASTM54 density and volume of crude oil or refined product

which can be used stand alone or with ISO 5167 computing module (by Flowing fluid Dia-log). Detailed descriptions for modules see in sections 3.2...3.11.

2.5 Energetical calculations in power station

Steam side energetical calculations in a power station or heat power station also can be made by SmartFlow. You can calculate for example

● useful heat power of power plant boiler● steam side energy flow of turbogenerator● pump required power and its useful water side power

You can calculate with use of SmartFlow also the incoming heat power and efficiency of a power station block from flow and calorific value of burned energy source putted into the block.Suitable energetical calculations for the aboves and more elements see in section 3.2.1.

2.6 Verification of flow computersfor differential pressure devices and others

In flow computer verification mode (section 4.3.2) SmartFlow can be used for verifica-tion and total uncertainty calculation of flow computer for differential pressure device and/or other flow meter. In this case SmartFlow leaves the standardized algorithm-uncer-tainties out of consideration but the input parameter uncertainties will be taken into ac-count. The uncertainties of input parameters come from secondary standards for signal

generation to flow computer. The generated current, voltage, Pt100 resistance etc. has total uncertainty for which in a suitable physical unit expressed quantity can be give in the uncertainty field belonging to the appropriate parameter input. By SmartFlow calculated result uncertainties from this characterize the Calibration and measurement capability of flow computer calibration. From this and standard deviation of displayed values can be calculated the total uncertainty of flow computer (detailed description see in section 4.3.2). From difference of flow computer displayed values to SmartFlow calculated res-ults the flow computer error can be calculated.

Flow computers for differential pressure devices can be verified by ISO 5167 mod-ule (section 3.1).

Flow computers for other flow meters, in case of natural gas can be verified by PTZ module (section 3.10) and of crude oil or refined pruduct by ASTM54 module (section 3.11). The PTZ and ASTM54 modules calculate also the right value of totalised base volume from line volume and vice versa. Furthermore the PTZ module calculates the de-livered energy by natural gas and the ASTM54 the delivered mass of crude oil or refined product.

2.7 Total uncertainty calculation of measuring tube

In default uncertainty-calculation mode SmartFlow calculates the total uncertainty of measuring tube complete with primary and secondary devices (normal mode). When the uncertainty of transducers (T, P, dP etc.) are correctly set, the total uncertainty of flow and delivered energy will be calculated by calculation described in section 2.2. In this case calculated uncertaintes contain both the uncertainties of input parameters (transducers) and algorithms (measuring tube).

Between normal and flow computer verification mode SmartFlow can be toggled by method described in section 9.3.

2.8 Delivered energy of natural gasby flow meter other than diff. pressure device

SmartFlow can calculate flow, energy flow or delivered energy from inferior or superior calorific value of natural gas flowing in flow meter other than differential pressure device. For this, use PTZ module (see 3.10)!


10/117


2.9 Mass flow of crude oil or refined productby flow meter other than diff. pressure device

SmartFlow can also calculate mass flow immediately from line volume flow measured by flow meter other than differential pressure device of crude oil or refined product. For mass flow calculation use ASTM54 computing module (see 3.11.2)!

2.10 Delivered mass of crude oil or refined productstored in tank

Furthermore SmartFlow can calculate the mass of crude oil or refined product de-livered into tank with significant accuracy from stuff, volume (base or line), hydrostatical pressure and temperature of liquid hydrocarbon. For this, use ASTM54 computing module (see 3.11.3)!

3. SmartFlow computing modules

3.1 ISO 5167 sizing and flow rate calculation of differential pressure devices

By ISO 5167 computing module of SmartFlow program you can size diameter of each primary device mentioned in ISO 5167 standard:

● Orifice plate● ISA 1932 nozzle● Long radius nozzle● Venturi tube 'as cast'● Venturi tube machined● Venturi tube rough-welded● Venturi nozzle

The suitable primary device can be selected by Primary device2 drop-down on Para-meter inputs | flowing fluid tab. The Flow standard3 can be

● ISO 5167:2003● ISO 5167-1:1998● ISO 5167-1:1991● GOST 8.563:1997

SmartFlow can also verify measuring tubes with above mentioned primary devices by above standards, so thus the Calculation type can be

● Flow rate calculation (2.2)● Diameter calculation of orifice (nozzle), (2.1)● Pressure difference calculation (2.3)

By flow rate calculation can be calculated flow rate, mass- and energy flow frompressure difference of fluid flowing in the known geometry measuring tube. By differen-cial pressure calculation the pressure difference at primary device can be calculated from known measuring tube geometry and flow rate. Flow rate calculation or differen-cial pressure calculation can be made for primary device either of known or SmartFlow calculated diameter.

3.1.1.1 Flowing fluid module windowThe flowing fluid in the measuring tube at line conditions is one of the most important

inputs for SmartFlow and ISO 5167 computing module. The flowing fluid properties can be calculated by Flowing fluid window appearing by press of Flowing fluid button. On this window visible edit boxes and drop-down categories are in accordance of selected Flowing fluid (on “Parameter inputs | flowing fluid” tab see in 3.1) by these the relevant physical input properties of flowing fluid can be set (Fix value) or calculated by selected SmartFlow module. In case of SmartFlow module calculations SmartFlow optimises the calculation sequence in accordance of selected standars and runs each module after the other in the right metrological sequience automatically. The user only acknowledges the next calculation (standard name) and sets the suitable inputs in the appeared computing module window (like by stand alone calculations) and presses the “Start calculation!” button in the actual window. After calculation the results will be acknowledged by pressing of “OK” button appeared on calculated results tab and transported automatically to the Flowing fluid window. (In case of an error or freudulent result the calculation can be re-peated as time as user want until acknowledged by “OK”.) When the all selected calcula-tion ran, the flowing fluid calculated properties can be transported to the ISO 5167 com-puting module window by pressing of “OK (Values to the 5167 window!)” button whereby this properties the suitable ISO 5167 calculation can be exactly performed (see 3.1 and 3.1.1 sections for start of calculation).

3.1.3 Verification of flow computersfor measuring tubes with differential pressure devices

By ISO 5167 module running in flow computer verification mode (4.3.2) SmartFlow verifi-cates flow computers for measuring tubes of differencial pressure devices. That means that uncertainty values at input parameters and calculated results represent the Calibra-tion and measurement capability of input signals of standards and right values of flow computer displayed quantites calculated from input parameters according to input signals. Displayed values can be simple calculated or totalised values (total volume and delivered energy of flowing fluid etc.) From SmartFlow calculated best measuring capabilities and standard deviation by flow computer displayed values the total uncertainty of flow com-puter can be calcula-ted (squear-root-mean calculation). From difference of flow computer displayed values to SmartFlow calculated results the flow computer error can be calcu-lated. These supplemental calculations from SmartFlow calculated values and measured results can be well automated by suitable spreadsheet. SmartFlow can export the calcu-lated results in *.CSV file or they can be copied by clipboard, selected one after the other.

By ISO 5167 module can be verified flow computers for differential pressure devices measuring natural gas, water, steam furthermore crude oil or refined product after suitable selection of flowing fluid.

3.2.2 Energetical efficiency and steam side energy flow of power station elements

To increase of energetical efficiency of power station it is important to know the effi-ciency of single energetical elements and for this it is necessary to calculate their heat power. For this use SmartFlow IAPWS-IF97 computing module (see Figure 8.)

m mass flow of superheated steam at inlet pipe (kg/s),

it1 specific enthalpy of steam in inlet flow (MJ/kg),

it2 specific enthalpy of steam at outlet flow (MJ/kg).

You can perform the above calculation simply from pressure and temperature of inlet and outlet pipe fluid and its mass flow with IAPWS-IF97 computing module like as in Figure 8.The efficiency of turbogenerator:

3.2.2.3 Required electrical power of pumpWith IAPWS-IF97 computing module you can calculate also useful water side power of

pump working in a power station circle.

Figure 11. Pump with ip1 inlet and ip2 outlet enthalpy

Pp = m ⋅ (ip2 - ip1) (10.)where: Pp useful water side power of pump (kW),

m mass flow of water at inlet pipe (kg/s),

ip2 specific enthalpy of water at pump outlet pipe (kJ/kg),

ip1 specific enthalpy of water at pump intlet pipe (kJ/kg).

You can perform the above calculation simply from pressure and temperature of inlet and outlet pipe fluid and its mass and also volume flow with IAPWS-IF97 computing module like as in Figure 8.

In case if you know the pump efficiency you can calculate required electrical power of pump or vice versa. Required electrical power of pump can be calculated as:

Ppv = Pp / ξp (11.)where: Ppv required electrical power of pump (kW),

Pp useful useful water side power of pump as in equation (10.) above, cal-culated by IAPWS-IF97 computing module (kW),

ξp pump efficiency (value between 0 and 1 without measurement unit).

Beside above ones you can calculate power and efficiency also power station elements other than above e.g. heat exchanger, condensator e.t.c. with SmartFlow IAPWS-IF97 computing module.

By AGA8 (SGERG) -G1 and -G2 module (named also AGA8-G1 and AGA8-G2) SmartFlow can calculate the base and line compressibilty factor of natural gas even if the total gas composition by AGA8 isn't known. The AGA8 (SGERG) -G1 and -G2 module calculates from superior calorific value, relative density, CO2-, N2 and H2 concentration (mol%) and base- and line pressure and temperature the base and line compressibilty factor of natural gas.

3.6 GOST 30319 compressibility factor of natural gasLike as AGA8 (SGERG) -G1 and -G2 the GOST 30319 compressibility factor module

can calculate base and line compressibilty factor of natural gas even if the total gas com-position in accordance of AGA8-DC92 isn't known. This module calculates the compress-ibility factors from base density, CO2- and N2 concentration (mol%) and base- and line pressure and temperature of natural gas.

calculate base and line compressibilty factor of natural gas even if the total gas composi-tion in accordance of AGA8-DC92 isn't known. Only from CO2- and N2 concentration (mol%) and relative density (and base- and line pressure and temperature) the base and line compressibility factor can be calculated. Uncertainty of this methode is just like as in AGA8-DC92 (ISO 12213) but the applicable range is between -23...+17 oC on 0...30 bar abs. and the relative density range is smaller.

SmartFlow can use calculated compressibilty factor values by Flowing fluid window also in ISO 5167 module for sizing or flow rate calculations of differential pressure devices (see 3.1.1.1, the values needn't be set again).

3.8 GOST 30319 dynamic viscosity and isentropic exponent of natural gas

GOST 30319 dynamic viscosity and isentropic exponent module calculates the dy-namic viscosity and isentropic exponent of natural gas. Like other SmartFlow modules this module also calculates total uncertainty of calculated properties. It needs as few para-meter inputs as AGA NX19mod (see 3.7) but base density instead of relative density.

31/117


3.9 ISO 20765 thermodynamic properties of natural gasLike GOST 30319 (3.8) the ISO 20765 module also calculates the isentropic exponent

of natural gas but also much more parameters like● Compressibility factor at line conditions● Molar density at line conditions● Line density

moreover● Internal energy (specific and molar)● Enthalpy (specific and also molar)● Entropy (specific and also molar)● Specific heat (isochor and isobar and also molar quantities)

SmartFlow also calculates on specific and molar basis this properties. Furthermore also● Isentropic exponent● Sound velocity

will be calculated. The isentropic exponent and line density SmartFlow can use by Flow-ing fluid window also in ISO 5167 module for sizing or flow rate calculations of differen-tial pressure devices (see 3.1.1.1, the values needn't be set again).

Calculated properties of natural gas by ISO 20765 module:

Compressibility factor at line conditions in ISO 20765 will be calculated by algorithm defined in AGA8-DC92 (ISO 12213) (see section 3.4), so thus the calculated result and its total uncertainty are entirely consistent with result calculated in AGA8-DC92.

3.10 PTZ density, volume and delivered energy of natural gas

3.10.1 General use of PTZ moduleThis module calculates from pressure, temperature and compressibility factor at base

and line conditions (P, T and Z) the following properties of natural gas ● density (line from base or vice versa)● base volume from line volume (and vice versa)● base flow or flow rate from line (and vice versa)

In case of volume or flow rate calculation● energy flow● delivered energy

also can be calculated from inferior or superior calorific value of natural gas.Line density can be calculated also from base or relative density. In case of total gas com-position the relative density can be calculated by ISO 6976 module (section 3.3). If total composition isn't known, fix value can be set. Base and line compressibility factor as input can be set as fix value or calculated by SmartFlow module selected from drop-down. In case of total gas composition is this drop-down list full otherwise either module can be se-lected except AGA8-DC92 (ISO 12213).

Like in Flowing fluid window in ISO 5167 module (section 3.1.1.1) SmartFlow optimises the calculation sequence in accordance of selected standars and runs each module after the other in the right metrological sequience automatically. Acknowledgeing the next cal-culation and setting suitable inputs in the appeared computing module window and press-ing the “Start calculation!” and done! It is like as in Flowing fluid window (see section 3.1.1.1) but calculation results are acknowledged by pressing of “OK (PTZ)” button (in-stead of simple OK) appearing on calculated results (or properties) tab.

Like as other SmartFlow modules PTZ also calculates the total uncertainty of all calcu-lated properties. To this PTZ also takes into account the uncertainty of each parameter in-puts.

– SmartFlow can use line density calculated by PTZ also by Flowing fluid window in ISO 5167 module for sizing or flow rate calculations of differential pressure devices (see 3.1.1.1, the values needn't be set again). PTZ can call other computing modules also in this case and transport calculated line density to Flowing fluid window transporting the density value away to the ISO 5167 computing module window. SmarFlow calculates dur-ing above calculations total uncertainty of all calculated results correctly and consistently.

3.10.2 Verification of flow computers for natural gas measuredby flow meter other than diff. pressure device

By PTZ module running in flow computer verification mode (4.3.2) SmartFlow verifies flow computers for natural gas measured by flow meter other than diff. pressure device. The uncertainty values at calculated results in this case represent the Calibration and measurement capability of right values calculated from input quantities (signals) having their uncertainties in accordance of best measuring capabilitiy of standards used for flow computer verifications. By flow computer displayed values can be simple calculated or to-talised values (total volume and delivered energy of flowing fluid etc.) From SmartFlow calculated Calibration and measurement capability and standard deviation by flow com-puter displayed value, the total uncertainty of flow computer can be calculated (through squear-root-mean calculation). From difference of flow computer displayed value to SmartFlow calculated result the significant error of flow computer at a working point can be calculated. Total uncertainty and error calculation can be well automatised by suitable spreadsheet program: SmartFlow can export its calculated results and uncertainties in *.CSV file (or they can be copied by clipboard). Deviation by flow computer displayed value also can be in spreadsheet well calculated. From these quantities can be easily a squear-root-mean calculated that the total uncertainty of flow computer at a working point means.

Parameter inputs and calculated results by PTZ as follows:

After selection of liquid hydrocarbon and setting of line pressure and temperature the desired density and other supplemental parameters with their uncertain-ties can be calculated.SmartFlow can use line density calculated by ASTM54 also by Flowing fluid window in ISO 5167 module for sizing or flow rate calculations of differential pressure devices (see 3.1.1.1, the values needn't be set again). ASTM54 can transport calculated line density to Flowing fluid window transporting the density away to the ISO 5167 computing module window. Line density can be calculated also from base or measured density.SmarFlow calculates during above calculations total uncertainty of all calculated results correctly and consistently.

The sheets can be collected in workbooks for totalising furthermore prognostisation of volume of crude oil or refined products.Parameter inputs and calculated results are like as in mass- and volume flow calculation methods (see table in 3.11.2) but volume-parameters are exactly volumes instead ofvolume flows.

3.11.4 Verification of flow computers of crude oil or refined productBy ASTM54 module in flow computer verification mode (4.3.2) SmartFlow can verify

4. TOTAL Uncertainty calculationby SmartFlow

SmartFlow calculates total uncertainty of all calculated results in all computing modules (see above sections 3.1 ... 3.11) from uncertainties and properties of

● parameter inputs● sensitivities● calculation methodes (algorithms) described in relevant standards

so thus total uncertainty calculation of parameters in SmartFlow is really TOTAL. Sensitiv-ities are calculated from partial differences by numerical mathematics.

4.1 Uncertainty and value of parameter inputs, sensitivity calculation

SmartFlow takes into account the given uncertainty value of all parameter inputs be-longing to any calculated result and also the uncertainty of this result if it may be aparameter input for other calculations, so thus the uncertainty spread is well traceable. This is especially important at ISO 5167 calculations of sizing or flow rate calculation of differencial pressure devices when also flowing fluid calculations will be made (in Flowing fluid window, see capture 3.1.1.1) and from calculated properties of fluid the ISO 5167 module makes further calculations. This is like also in PTZ-module calculations. Since the total uncertainty calculation always springs from uncertainties given by us at parameter inputs it is very important that the given uncertainties may be right values. In this case the calculated uncertainties at results may be also right. Some parameter input uncertainties can be taken from plan or layout (tolerances e.t.c.) or other documentation of measuring tube, e.g.:

Figure 14. Geometric sizes and their uncertainties (tolerances)

Other parameter uncertainties can be got from data sheet or calibration certificate, e.g.:


42/117


Figure 15. Uncertainties of parameter inputs by transducers (from their data sheet)

Important: %-values are according to RDG and not to FS values!

4.2 Defined uncertainty of calculation methodes in relevant standards

Normally, SmartFlow takes into account upon uncertainties above (see 4.1) also uncer-taintes defined and described in relevant standards containing algorithms belonging to the selected module. It goes for all SmartFlow-modules described in captures 3.1...3.11.

Figure 16. Uncertainties (from parameter inputs and algorithms defined in standards)

At calculations described above SmartFlow calculates total uncertainties of calculated re-sults always correctly in accordance to relevant standards (ISO, AGA, IAPWS e.t.c).

– When the parameter input uncertaintes are 0, the program at this time calculates un-certaintes of results but these are uncertaintes of selected calculation. Algorithm-uncertainties are also defined in standards containing some the algorithms.


43/117


4.3 Uncertainty calculation methodes in SmartFlow according to applications

4.3.1 Normal modeNormal mode (= NON Flow computer verification mode) is the default SmartFlow un-certainty calculation mode. In this mode will be taken into account also incertainties described in the above sections 4.1 and 4.2 . Normal mode is for total uncertainty calcu-lation of complette measuring tube. Uncertainties of calculated results marks the wholemeasuring tube containing primary and secondary elements and flowing fluid. When you see in frame window the title "SmartFlow" and nothing else, the program is in normal mode and also takes into account the algorithm-uncertainies belonging to primary device (measuring method) and flowing fluid.

Figure 17. Normal mode: Only the "SmartFlow" programname is in frame window title

In this case calculated total uncertainty typical values are visible on figure 16.

4.3.2 Flow computer verification mode,total uncertainty of flow computer

Flow computer verification mode is in SmartFlow for verification and calculation uncertain-ties of calibration belonging to flow computers working at pressure difference or other flow meter measuring tubes. In this case SmartFlow takes into account the parameter input uncertainties only (see 4.1) and passes by algorithm-uncertainties of primary elements and flowing fluid. Parameter input uncertainties are belonging to input signals and in this case calculated result uncertaintes represent the Calibration and measurement capability of flow computer calibration. From SmartFlow calculated Calibration and measurement capability and standard deviation by flow computer displayed values the total uncertainty of flow computer can be calculated (squear-root-mean calculation). From difference of flow computer displayed values to SmartFlow calculated right values the (systematic) er-ror of flow computer can be calculated. These supplemental calculations from SmartFlow calculated values and measured results can be well automated by suitable spreadsheet.


44/117


SmartFlow can export the calculated results in *.CSV file or they can be copied by clip-board, selected one after the other.

- From normal mode to flow computer verification mode changing see in capture 9.3. and also "[flow computer verification]" appears in the main frame window title:

Figure 18. Flow computer verification mode (see in the main window frame!)

In flow compoter verification mode calculated total uncertainty values are smaller than values in 4.3.1 and contain parameter input uncertaintes and their sensitivities only and pass by algorithm-uncertainies. This uncertainies represents the Calibration and mea-surement capability of flow computer calibration and are significant smaller than in 4.3.1:

The registration program helps for user to register the program. You can see the necessary steps for registration. Fill this dialog and send us the registration mail automatically generated by pressing “Send the e-mail for registration”. Your e-mail with the necessary dates will be sent to [email protected] and the specialists in the Gamma Digital Ltd. will you send activation codes to required software components to register them at the first run of frame program and also computing modules. The computing modules required by user can be separately registered and activated. You needn't register each computing modules for use a module but only the frame program and modules to use.


58/117


In case of Demo registration „DEMO” checkbox will be checked. (Figure 32. Computeridentification window for registration ) In this case the serial numbers for demo registration will be automatically generated by the setup program. You can right away send your e-mail us! Demo version may be also registrated but this registration is totally free. -In case of full version you have to set in “Serial number(s) of module(s)” box serial numbers became from GammaDigital Ltd. and the “DEMO” checkbox must be unchecked!

You can run registration program also later e.g. when you change hardware elements on your computer running SmartFlow. For this run Register.bat in folder: Program Files\GammaDigital\SmartFlow\Register.bat

This runs the registration program (see computer identification window above). If you don't have internet connection to register the program, you can save the registration mail and send it later (also from an other PC).

Sample e-mail for registration requiring:

description you can select the calculation by the select calculation window (Figure 41.)After selection the suitable calculation module window starts and appears with default

values in main window. You can open in the main window as many module window as you want!

9.1.2 Open...You can open a saved calculation. The calculation appears as you saved it. You can-

not open calculation in demo mode.


67/117


9.1.3 Load into active window...A saved calculation can be loaded into a window other than its original window. The

content may be loaded always into the active window. Attention: If you receive parameters and results (e.g. gas composition) from other

module window with this method, you may take it before setting head (see in 12.3.1) or other inputs to avoidance overwriting them!

– This menu function is not available in demo version.

9.1.4 Gas composition import from *.xls(x)... data files

With this menu item you can get total gas composition in any computing module win-dow for validated SmartFlow calculations immediatelly from *.xls or *.xlsx Excel filescoming from gas chromatograph or other way. It can be also AGA NX19mod window whether any other module window don't contain all gas components. You can import gas composition into Flowing fluid window coming from ISO5167 module whether PTZ win-dow and other modules coming from it. You can import gas composition from all gas chro-matograph types saving it into *.xls or *.xlsx data files.

The *.xls(x) files coming from chromatograph or other way can have any strukture and components can be also in different worksheets. Further description for this menu item see in Section 11.

Attention: If you will set any gas component to a fix value then do this after gas com-position import to avoidance its owerwriting by import.

– This menu function is not available in demo version.

9.1.5 Save...You can save your calculations in your full program version.

9.1.6 CloseYou can close the active computing module window.Before closing you can confirm it (except if the calculation was already saved):

11. Calculations from gas composition coming from gas chromatograph,

*.xls or *.xlsx data files

With SmartFlow you can make calculations from gas composition coming from gas chromatograph, *.xls or *.xlsx data files in any computing module window. To this you can import composition easily with some click from chromatograph types saving composition into Excel compatible *.xls or *.xlsx data files. From imported composition in any module window SmartFlow can calculate.

This importation method is usable also in case of *.xls or *.xlsx data files generated by user without any chromatograph.

11.1 Benefits● Gas composition from *.xls or *xlsx data files can be imported into any computing

module window wheter into Flowing fluid window (coming from ISO 5167 module) or PTZ window or other windows coming from them

● Gas composition can be from any Excel version generated *.xls or *.xlsx data file● The *.xls or *.xlsx data files can be generated by user haven't a chromatograph● Structure of *.xls(x) files can be any and gas components can be in different works-

heets but only the files must have a some predefined structure

11.2 UsageGas chromatograph saves gas composition generaly into a predefined file path and di-

rectory. To import:1. Select or run SmartFlow computing module window in which you want to calculate

from gas composition


78/117


2. click on toolbar on Gas composition import from *.xls(x)... button (see Figure 56 or select in File menu the menu item with some name).

3. In the appeared file selection window:

Figure 57. Excel *.xls(x) file selection window for gas composition loading

open selected *.xls(x) data file on desired path and4. confirm file opening (check file name):

Figure 58. Confirmation to the selected *.xls(x) data file


79/117


5. wait to this message:

Figure 59. Loading succeeded message at end of process

Loading is complete when this appears. (Running time of this loading method may be up to 5...8 seconds at the first time after program start. Further loadings will be faster.) From *.xls(x) loaded components are with coloured background (concentration unit and gas components) on ISO 6976 computing module window Parameter inputs... tabs:

Figure 60. Loaded components with cloured background in ISO 6976 window

From imported gas composition you can calculate properties (with Start calculation! button).


80/117


Attention: Due to Windows features this gas import service of SmartFlow is available only in 32-bit (x86) Windows. If on your machine is a 64-bit (x64) Windows version and you want to use this service, install SmartFlow on a 32-bit (x86) Windows machine or virtual machine with 32-bit (x86) Windows installed on your computer:

Figure 61. Gas composition import is available in 32-bit (x86) Windows

When provider resource for reading data from *.xls(x) data files in 64-bit (x64) Windows systems will be later ensured so you can import gas composition also in these Windows versions.


81/117


11.3 Flexible systemSmartFlow imports gas composition from *.xls(x) data files with any structure according

to SFL_GAS_COMP__PREDEF.XLS predefinition file containing Sheet and Cell names of gas components data source in these files. The predefinition file is in the SmartFlow modules directory what is in case of default installation:

C:\Program Files\GammaDigital\SmartFlow\Modules\This folder is hidden but it can be visible with a suitable file expolorer. Strucure of pre-definition file in this folder is:

Figure 62. Structure of SFL_GAS_COMP__PREDEF.XLS file (continued)

Column Name MeaningA ID parameter ID

B Type parameter typeC Name parameter nameD Sheet worksheet on which parameter occursE Cell cell in which parameter isF Valu parameter value (if it don't come from *.xls(x) data file)G Remark remark to parameter

Last four columns are editable. User can set all parameters data source Worksheet and Cell in *.xls(x) data files structure. In case of fix value set “-” (minus) character into Sheet and Cell column belonging to parameter (don't leave these cells empty!) and set it's value! System security aspect set cells in Value column of all parameters above this first row to zero (see Figure 62) otherwise you will receive an error message. (In cells of column Value belonging to parameters below it isn't necessary.) Save predefinition file with correct settings (owerwrite the older file)! In case of right operation at a gas composition import appears a message like as in Figure 59. So you can adjust SmartFlow to all gas chromatograph types saving gas composition into *.xls(x) data files.


82/117


In case of error message or other problem ask colleague of GammaDigital Ltd! Further help is solving problems in Section 11.5!

11.4 Import newest *.xlsx files in earlier Windows versionsYou can import gas composition into SmartFlow from *.xlsx data files in Windows

version earlier than Windows7 but in this case install provider Microsoft Access database engine 2010 (English)! You can download it from web page of GammaDigital Ltd. or Microsoft. It isn't necessary to *.xls data files because of provider to these files is part of all Windows versions suitable to use SmartFlow.

11.5 Error Messages – SolutionsAppearing error messages and solutions of errors during gas composition import from

*.xls(x) data files are follows:

11.5.1 SFL_GAS_COMP__PREDEF.XLS could not be found

Figure 63. SFL_GAS_COMP__PREDEF.XLS could not be found!

Solution: If you have a back-up copy of the file, copy it into above path (this path is hidden, but many file explorers can display hidden folders), if not, reinstall SmartFlow-t (see in Section 6.2). In this case predefinition file settings (Section 11.3) may be required.


83/117


11.5.2 Could not connect to the predefinition file

Figure 64. SmartFlow could not connect to the predefinition file!

Solution: If the predefinition file was saved as password-protected workbook, save it from Excel with workbook protection but without password! If the problem persists, contact GammaDigital Ltd. colleagues!

11.5.3 Could not connect to selected *.xls(x) data file

Figure 65. SmartFlow could not connect to the selected *.xls(x) data file!

Solution: If the file was saved as password-protected workbook, save it from Excel without password! If the problem persists, contact GammaDigital Ltd. colleagues!

11.5.4 Could not open „GasCompAddresses” worksheet

Figure 66. SmartFlow could not open „GasCompAddresses” sheet in predefinition file!

Solution: Rename from „GasCompAddresses” renamed worksheet to its original name again. If this does not help, contact GammaDigital Ltd. colleagues!


84/117


11.5.5 Type-mismatch errors or cell is empty in predefinition file

Figure 67. Type-mismatch error in .SHEET datamember or cell is empty!

Figure 68. Type-mismatch error in .CELL datamember or cell is empty!

Figure 69. Type-mismatch error in .VALUE datamember or cell is empty!

Solution: Open the predefinition file (see in Section 11.3) in Excel and enter correct data value in the problematic data cell (as in Figure 62). Save the file. If during the loading these above errors continue occur, fix them! Above the first row containing Cell and Sheet pulled out („-”) set all cells in Value column to zero (Figure 62 in Section 11.3)! It is for system safety requirements necessary. Below this row it isn't necessary. To dialog boxes: Header of table is the first row of table !


85/117


11.5.6 Non-interpretable data or cell is empty in selected *.xls(x) data file

Figure 70. Non-interpretable data or cell is empty in selected *.xls(x)!

Solution: Open selected *.xls(x) data file in Excel and look data in indicated cell on Worksheet! If this cell is blank or type-mismatch (text instead of numeric value), this error message will be occured. If the value is numeric value and this error message persists, contact GammaDigital Ltd. colleagues!

11.5.7 Worksheet or cell doesn't exist in the selected *.xls(x) data file

Figure 71. Worksheet or cell doesn't exist in the selected *.xls(x)!

Solution: This message appears if you want to import gas composition from a file doesn't contain gas composition (mistakenly opened wrong file). Select a data file containing gas composition. If the problem persists, check reference in the SFL_GAS_COMP__PREDEF.XLS predefinition file. Sheet and Cell values must be in accordance to actually imported *.xls(x) file structure and must be aligned to it (refer to Section 11.3)! Align Sheet and Cell references to desired structure if necessary!


86/117


12. Computing module window in use

Computing module window structure and usage will be presented for example on a ISO 5167 computing module window flow rate calculation. The structure of other comput-ing module windows is generally as like as this.

12.1 Start a calculationYou can start a calculation with New calculation in File menu or toolbar button.If you have demo version, first appears a limitation message box about limitations in

demo module window. (This don't appear in full program version.)In case of ISO 5167 demo module window this message box is:

Figure 72. Limitaton message when ISO 5167 demo module window starts

Press OK to continue if this message box appears.

12.2 Scrolling a window in main windowIf a computing module window breaks leave the main window (its part is out of main

window), it can be scrolled by mouse wheel or vertical scroll bar in SmartFlow main win-dow. If no any window leaves the main window area, the vertical scroll bar disappears.


87/117


12.3 StructureSmartFlow computing module window when it starts:

Figure 73. ISO 5167 computing module window when it starts

12.3.1 HeaderBetween window title and tabs are the most relevant identification dates to identify the

calculation. Calculation (ID) and Meter run / plant / working (ID) are always visible above the tabs independent of selected tab.


88/117


12.3.2 TabsParameter inputs and calculated results are in a computing module window grouped in

tabs.

12.3.2.1 User data itemsOn this tab you can input relevant identification characterizing the calculation and refin-

ing the most relevant (ID) dates above. You can give also remarks to calculation.Input fields are: Date; Time; User name; Short description; Remarks.


89/117


12.3.2.2 Parameter inputs

Figure 74. Parameter inputs tab in ISO 5167 computing module window

Parameter inputs to a calculation can you enter an parameter inputs tab in a computing module window.

Some parameters can be set by drop-down. If you change a drop-down, some para-meters below this can be modified, appeared or disappeared according to desired calcu-lation. By changing a drop-down, only parameters below this may be modified and para-meters above this stay unchanged. So you can input parameters from up to downstairs moving in an order comfortably in a window. (This is true for each computing module win-dow!)


90/117


Same parameters cannot be modified, these are only for user information.Uncertainties after “+” belonging to numeric parameters can be set or read only.Start calculation button is always on a parameter inputs tab below of last parameter

input. On the next tab(s) are calculated parameters (and also detailed inputs if these are enabled, see Figure 50 in section 9.3. In this case in ISO 5167 module you can see Start calculation button after them.)

12.3.2.2.1 Parameter setting's direction in modules

Tab changing direction is left to right and parameter setting direction is up to down.

Figure 75. ISO 5167 window – Recommended direction of parameter setting


91/117


SmartFlow benefit: You needn't set again a parameter or dropdown above the currently changed one!

12.3.2.2.2 “Start calculation!” buttonAfter parameter inputs you can start your desired calculation by this button. By press-

ing this button results appear if there is everything properly. But if one or more parameter inputs are out of range of calculation method you will get a message box to stop or contin-ue the calculation.

12.3.2.2.3 “Flowing fluid” buttonBy pressing this button appears a Flowing fluid window containing parameters be-

longing to flowing fluid selected in the ISO 5167 module window. Parameter inputs entered by user in the ISO 5167 module window are automatically transferred to this win-dow, so you need input only parameters belonging direct to flowing fluid. It is very com-fortable to use and mistaking is minimal.

Calculated parameters in Flowing fluid window will be calculated than by other mod-ules called by this window.


92/117


12.3.2.2.3.1 Flowing fluid window

Figure 76. General inputs tab in Flowing fluid window

General inputs are on tab above, further inputs and calculated parameters are on the next tab “Fluid particular properties”.


93/117


Figure 77. Flowing fluid window particular properties

In calculation method drop-downs appear module names only installed on your PC therfore you can select leisurely these methodes and SmartFlow performs sure the selec-ted calculations.

You can start the calculation of properties by “Calculation of fluid properties!” button. The calculated properties and their uncertainties according to relevant standards belong-ing to selected methodes appear below the drop-downs.

Press “OK (Values to the 5167 window!)” button to transfer calculated properties to ISO 5167 computing module window. (By pressing Cancel (close) you will close this win-dow without transfeerring any parameter to ISO 5167 window.)


94/117


12.3.2.3 Calculated results

Figure 78. Calculated results in ISO 5167 computing module window

On this tab you can see the calculated results with coloured background. (Other para-meters aren't in this calculation calculated because of settings by user or the parameters are simple informative parameters).


95/117


12.3.2.4 Detailed resultsOn this tab you can see detailed results with coloured background. (Other parameters

aren't in this calculation calculated because of settings by user or the parameters are simple informative parameters). – Some computing module window haven't detailed res-ults tab.

12.4 Parameter fields, their content and edition

12.4.1 Measurement units useSome parameters measurement unit can be set by drop-down.Apperance of an editable or non-editable field is different when their measurement unit

will be changed.

12.4.1.1 In case of editable parameter inputsIt is recommended and also comfortable to fill parameter inputs from left to right side so

first set the value of parameter input than select its measurement unit by drop-down. In this case drop-down after the parameter input hasn't any effect to the value in input field. If you will also convert input value into other unit for this use the other drop-down after “+” and uncerty value. If you change this drop-down, the parameter input will be convert into the other unit selected by drop-down.

Parameter input values will be taken into account for the calculation method always with their measurement units selected by dropdown.

12.4.1.2 In case of non-editable fieldsUser cannot modify the values by edition of calculated results or non-editable parame-

ters but in case of several measurement unit they can be converted into other unit by drop-down either after the parameter field or its uncertainty field. The effect of both drop-down is same.

12.4.2 Invalid number format error handlingIf the user types a number wrongly (wrong character) into data field, SmartFlow sends

an error message about invalid number immediately :

Figure 80. Error message in SmartFlow – invalid number format


97/117


Also the background of input data field will be red and the cursor blinks after the wrong character; it can be by a BACKSPACE deleted. (If the user types other wrong character, program sends an error message again.)

Figure 81. Red background in input field while invalid number format

12.4.3 Calculated resultsCalculated results appears mostly in non-editable fields on calculated results tab in

module window. In case of all right their backgrounds are green:

Figure 82. Calculated result field in SmartFlow

In case of step over the upper or lower limit defined in relevant standard or recom-mendation the background is red.

12.4.4 Out of range values handlingIn each computing modules will be checked all input values and calculated results ac-

cording to upper and lower limits defined in relevant standards and recommendations. Some standards and recommendations can define also general and wide applicable

ranges for physical quantities.

12.4.4.1 In input fieldsLimit overriding is indicated in any input field already by typing an input character. In

this case the character colour will be changed from black to any other.

13. Printing calculation report

You can print in SmartFlow the complete calculation. The well formatted calculation ri-port contains all parameter inputs and calculated results, from this the calculation is com-pletely reconstruable.

For printing use File menu Print... .You can use also Print preview... menuitem which visualizes a preview of printing. You can print also by Print... button on this preview.

You can set also separator characters for printing (see in capture 9.3.1.).

You can select and set printer by File menu Printer settings... menuitem. You can do it also in Print... and also Print preview... items.


100/117


Figure 89. Print preview in ISO 5167 computing module

In print preview you can scan the whole parameterlist by Scroll up and Scroll down buttons but you can use for this also mouse wheel! You can scroll the also by vertical scroll bar.

Print preview contains all parameter inputs and calculated results always according to active computing module window. Parameters are grouped in the list according to tabs.

You can access Print preview..., Print... and Printer settings... menuitems only when at least a computing module window is opened. Otherwise they are disabled.

Remark: Printer preview, print and printer setting can you access in SmartFlow full version

only. In case of demo version this functions are disabled.


101/117


14. Save and load calculations

14.1 SaveThe complete calculation can be saved into *.sfd datafile. For this use File menu Save... menuitem. In the appeared save window type file name

or select a file to vervrite it. You can change and also define directory.

Figure 90. Save file window in SmartFlow (e.g. ISO 5167 module is active)

If save is finished successfully, appears a message box containing the file name to receipt it.


102/117


Figure 91. File name including reception box after successfully save

In file names isn't recommended to use '.' (point)! It doesn't make any program error but file names containing '.' appear only in All files(*.*) view!

In case of overwriting a file appears a confirmation box:

Figure 92. Confirm file overwriting

In case of wrong file name we get error message (unexpected characters in filename etc.):

Figure 93. File name error message

14.1.1 In case of ISO 5167 or PTZ calculation saved files contain also the material properties

If you calculated a measuring tube with differencial pressure device or other flow meter by ISO 5167 or PTZ module, it is enough to save the calculation from this module win-dows. The saved files will contain also the flowing fluid properties calculated by other modules called by these computing modules. From files can be later the whole calculation method reconstruated by simple opening them. It is very comfortable and presumtion of a mistake is minimal.


103/117


14.1.2 Verifying a measuring tube in more working pointsIf you need to verify a measuring tube in differential working points, it is in SmartFlow

very quiet: If you have calculated and saved the first working point, you can open this than as times as you want and modify parameters only different in other working points. The calculation of other points is than very easy. Certainly you can than also save these points.

Different measuring tube calclations may be saved in different maps. You can than easy find them. You can save calclations belonging to same tube in also different maps by time or date than later you can compare the calculated results.


104/117


14.2 OpenYou can open your saved files by File menu Open... menuitem. File name can be se-

lected from file list or set in Filename field. The selected calculation will be open in a new window exactly some as it was saved.

Figure 94. Open file window in SmartFlow


105/117


14.3 Load into active windowSaved calculations can be loaded into active window. Parameters occur in saved cal-

culation and also in the active module window will be in window overwritten. For loading use File menu Load into active window... menuitem.

File name can be selected from file list or set in file name field as like as in save or open (section 14.1 or 14.2).

Figure 95. Load file window in SmartFlow (e.g. ISO 5167 module is active)

You can also change directory from its the file will be loaded.Before loading and overwriting you get a confirmation box about overwriting parameters in active window.

14.3.1 Coloured background at loaded parametersIn case of successful loading you get a receipt box about success, the tab after User data items tab will be activated and backgrounds belonging to loaded parameters will be co-loured (other parameter backgrounds stays uncoloured, they isn't in the loaded data file). Measurement unit backgrounds stays always white.


106/117


Figure 96. Receipt box and coloured backgrounds after successfully loading

Input field backgrounds on User data item tab and most relevant identification back-grounds in header of window stays always white also if they will be overwritten.

If Calculation (ID) field isn't empty, the compoting module window title will be identical with its content (and original title refer to type of window will be behind this in round brack-ets). It operates also by typing Calculation ID in the field.

- These appears also by opening a calculation (see capture 14.2).


107/117


14.3.2 Activity of menuitems belonging to active windowSave... and Load into active window... menuitems in File menu relates always to act-

ive window. Both menuitems are active only if you have at least one computing module window opened in SmartFlow main window. File and directory selection in this menuitems are identical as in most windows applications. In case of non-acceptable characters in file- or directory name or non-existing file or diractory user gets an error message.

14.3.3 Parameter transferablity between different type computing modules by file loading

For flowing fluid properties calculation in ISO 5167 window you can load a file coming from whatever any kind of computing module into ISO 5167 or Flowing fluid window (Fi-gure 74 and 76). Mostly usable files are for this files coming from other ISO 5167 or ISO 6976, AGA8_92DC (ISO 12213) or ISO 20765 computing module window containing total gas composition. You can load file coming from PTZ module also if it contains total gas composition or partial gas properties.

You can load in any computing module window files coming from whatever any kind of computing modules, the loaded and therfore overwrited parameter backgrounds are al-ways coloured (see in capture 14.3.1).

Due to aboves, the parameters occuring in different types of computing module win-dows are full transferable by files in SmartFlow.

But it is important to take into account that some parameters are stored eventuelly with their default value in files coming from other module. The most frequent reason for this is that these parameters wasen't immediately used in those calculations because of other flowing fluid than now desired or e.g. gas properties wasn't calculated from total gas com-position in opposite of current method. To avoidance the mistaking use it is recommended to store calculations for different measuring tubes and flowing fluids in different folders (see also capture14.1) It is also recommended to fill all data on User data tab to identify calculations (Figure 73).

Important: If you load a data file into a computing module window, it may be the first step because of the parameters contained also by data file will be overwrit-ten! You may edit only after this loading the parameter inputs! This refers also to User data items (12.3.1)!

Save and Load into active window menu functions mentioned in capture 14.1 and 14.3 can you access only in SmartFlow full version. These functions aren't accessable in demo version.


108/117


15. Program use in english and hungarian language

After installation you can use SmartFlow in english and also hungarian language. You can change language also during use, its effect appears immediately in all menu items, titles, and other window element captions in SmartFlow frame program and all opened comput-ing module window.Furthermore you can change language also after calculation so you can print report on language different from used during calculation.

15.1 Language selection and change during useYou can select language in Settings menu Language (see also 9.3). Currently you

can select english and hungarian language. The effect of language selection appears im-mediately in program on all window elements and captions so Settings menu Language menuitem Hungarian (HU) and English (EN) will be in hungarian “Beállítások” menü “Nyelv” menüpont “Magyar (HU)” és “Angol (EN)”. By these you can return to original language.

The language change of course hasn't any effect to operation of program and calcu-lated results. You can change language during calculations as times as you want!

15.2 Printing calculation riport on other languageYou can print your calculation on language other than used during calculation. In this

case the document will be printed on other language. (about printing see also capture 13). You can use than the original or selected new language.Important: Alphabetical caracter inputs may be on language identical to language dur-

ing report printing!

16. Error messages

16.1 Invalid number formatInvalid number format messages see in capture 12.4.2.

16.2 Warning message boxesSmartFlow verifies during calculation in each computing module the limits and other

applicable conditions defined in relevant standards and recommendations. In case of any deviation immediatelly appears a message box and you can decide to cancel or continue the calculation:
