Installation and operation of the

MODULAR DOSING SYSTEM SERIES MID- MDS

1.Application:

The Modular Dosing System MID-MDS is used on both linear and rotating filling machines, where high accuracy/repeatability is required. The products must have a minimum conductivity of approx 1 µS/cm. The minimum dosing time achieved to date is approx. 0.1 sec.Magnetic Inductive Flow Meters series MID have no moving parts, and therefore do not apply any "work" to the product which could cause changes to the fluid structure. This also enables CIP/SIP procedures to be carried-out both easily and quickly.

2. The dosing system MID-MDS consists of the following components (Fig.1):

- magnetic inductive flow meter series MID with standard frequency field design, with integral pre-amplifier

- dosing control ( electronics ) series MDS:

* converter card type UV- 12 * master card type DR- 11 with integral pulse output

* counter/valve card type LS- 23 * LAUER operator terminal

* housing for card installation: panel housing type MDS-30 ( 30 TE ), or panel housing type MDS-49 ( 49 TE ), or 19" rack mounting type MDS-84 ( 84 TE )

3. A filling system/installation generally consists of (Fig.2):

Fig.2

Systems with very short dosing times ( min. 0.1 to some sec. ) need a storage ( buffer ) tank-see Fig.2- the level of which must be kept more or less constant, e.g. by using a level control system, which automatically opens and closes the feed line to the storage tank. This arrangement supplies a dosing curve ( lapse ) as shown in (Fig.3):

1- stage valve closing

At time A the filling machine starts the batch process and thedosing valve opens. The magnetic flow meter measured theproduct; the sensed signal is send to the dosing control and alsoto the preset counter. At the end of the batch (B) the dosingvalve receives the signal to close. Because of delay time in thesystem ( mainly the valve ) a certain excess volume passes thedosing valve until it is closed and the batch process is finished(C).

2-stage valve closing

It is possible to decrease the excess volume if a 2-stage valveclosing is used. If the valve receives the prebatch signal ( B ),then the valve closes to a interposition.If the valve receives the finalbatch signal ( C ), then the valvecloses completely.These kind of valve closing should also be used if - the meter size is > DN 20 or - the batch is > 0.5 l / sec.- the velocity in the pipe is > 5 m/sec.

4. The components of a filling system should meet the following requirements:

a) storage tank ( no pressure, head of liquid only )

The tank dimension ( dia.,height ) should be such that a batch process ( one filling ) only causes a very small level variation ( decrease ). In the event of a large variation, the head ( gravity ) decreases rapidly, the excess volume is altered ( Fig.4) and both accuracy and reproducibility vary.

Fig.4

Due to the decreasing head of liquid, the flow velocity and the flow rate decrease, resulting in the dosing time becoming longer and longer ! This effect should be avoided if the dosing time is to be kept constant.

To keep the filling times constant, the liquid level head should be kept within 5% .

At bigger meter sizes (> DN 15) theliquid level must be more then 30 cm.If the level < 30 cm, Vortex-effects arepossible and resulting accuracy vary. ( A ).

To prevent vortex effects a build -in straightener is advantageous.

Very important is the position of theproduct line in the tank. The outlet ofthe pipe must be under the liquid level (B ). In other case, air bubbles are in theproduct and resulting accuracy vary.

b) piping

Whenever possible rigid metallic piping between storage tank and dosing valve should be installed. If flexible hoses are used, hydraulic vibrations could disturb the batch processes. The piping should be of the same size( DN;inner dia. ) as the magnetic inductive flow meter in order that the system can be deaerated easily.

Hydraulic vibrations are be created, if e.g.diaphragm, hoses or buffer tanks areexisting.The energie in the liquid is decreasedwith the oscillation of the liquid.

If the velocity cross the creeping flow ( B ), the pulse output in the convertercard is switched off.

If a new start pulse is comming duringoscillation, the velocity in the pipeincreased ( C ).

If hoses are used, then the hoses must be metal cased.

c) dosing valve

The dosing valve is very important for the accuracy/reproducibility of the dosing system.Attention should be paid to the following parameters:

c1) closing time: the closing time of the valve has to be in a certain ratio to the dosing time ( A to B ); the shorter the dosing time the shorter the valve closing time.

Guideline:

<<< the valve closing time should be not more than 10% of the dosing time >>>

If it is more than 10%, the dosing control is only able to register the size of the excess volume, but will not be able to react to it ( i.e. compensate/correct it for the next filling ). This effect can only be avoided by using a

two-stage shut-off ( two valves ), where the 2.nd ( final ) stage can compensate/correct alterations of the 1.st ( pre- ) stage.

c2) power supply: whenever possible a DC supply should be used to avoid the influence of the shape of sine waves of the AC supply. This is especially if the valve closes with voltage; the valve starts to close when the sine wave has exceeded the starting voltage; in the worst case this can take 10 ms ( 50 Hz field ) and so cause variations of the batched quantity ( in accuracies ).

c3) dosing valve: it is important that only a small volume isdisplaced during the closing procedure. The displaced volumeis part of the measured quantity and thus influences theaccuracy and reproducibility of the complete dosing system. Itshould therefore be kept as constant as possible! An instabilityof the displaced volume can effect the accuracy of systemswhere small quantities are dosed. Diaphragm valves withmetallic body are recommended, where a diaphragm of asynthetic material ( plastic ) is oppressed onto a metallic edge.This design has another positive effect: fruit particles andsimilar solids to be dosed are squeezed off the valve seat.

Diaphragm valve type 625 ( GEMÜ )

5. Description of the components

a) magnetic inductive flow meter series MID has an integrated and detachable pre-ampifier. The coils for themagnetic field requires a 24 VAC power supply.the cable for interconnection of the meter and the converter card isapprox. 5 m long ( if a length of more than 5 m is required ( max. 200 m ), an extension cable of same type isadmissible ). In the event of a malfunction the pre-amplifier can be detached and replaced; no calibration of thereplacement is required! The pre-amplifier is connected via plug and socket. The meter can be installed eitherhorizontally or vertically. Vertical installation is preferred for better deaeration; and also depositsare less likely to betrapped in the meter. In the case of horizontal installation the electrodes must be in horizontal position, i.e. thepre-amplifier must be above or underneath-but not beside- the meter body. If the meter is used together with aconverter card UV-12 the flow direction ( right to left/left to right or from below to above or vice versa ) of the meteris insignificant. The UV-12 switches automatically to the given flow direction and measurement can be startedimmediately.

Cables for power and signalesIt´s not allowed to install the meter or the electronik in an area with strong magnetic fields. The Measuring cablemust be install separatly from cables with power or controlsignals. The best solution is the installation for themeasuring cable in a grounded pipe of metal.

Installation guideline for transmitter

Inlet/Outlet

For a optimum flow profile it must be installed flow straightener behind and in front of the meter.This can be berealized. with straight pipes in the upstream- and downstream pipework.The upstream pipework must be 5 x DN and the downstream pipework must be 3 x DN. It´s not allowed to installany kind of devices upstreames. It´s forbitten to install in front of the upstream pipework devices which producedeffects like spin or vortex, e.g. space bend, butterfly valves or slider. Any regulation devices must be installedbehind the meter. Inclinations must be rotational symetrical and the angle should be < 8 °.The upstream-,downstream pipework and the meter must have the same diameter !!

Ground connection for the transmitter

The transmitter don´t need additional ground connections. Since the transmitter use the pipe potential asreference, the upstream-and downstream pipe must be on ground. The installation of the meter in plastic pipes is not allowed.

The power supply 24 VAC should be also on ground.

Mounting position of the transmitter

It must be insure, that the meter tube is allways completely filled during measuring and is protected againstasymetric formation of deposits. The vertical position is preverred, since it is simple to make the pipe airfree.

Is the meter is installed horizontal, then it must be insure, that the electrode axis is also horizontal.

Pipework must be supported adjacent to the meter and connections and provide 3° slope for draining..

If the electrode axis is vertikal, then air bubbles can be isolate the electrical connection between the electrodes and the product.In this case the output signal is undeclared

Laying of the measuring cable

It´s forbitten to install the meter in areas with strong magnetic fields. The measuring cable must be lay separatelyfrom power cables and control cables.To lay the measuring cable in grounded metal pipes is recommended. Measuring cables can be routed togetherwith other measuring cables.

Installation guideline for the electronics

General:

It is forbitten to install the electronics in areas with strong magnetic fields. The wiring must be depending from thefunction of the cables :

cables for signals e.g. start, errorcables for control e.g. cable for control the diaphragm valvescables for measuring e.g. measuring cable between the meter and teh electronicscables for power e.g. 24 VDC, 24 VAC , power for motors

Cables for signals or cables for control can be routed together to a multiple cable.

Measuring cable must be routed with the same cable typ. It is not allowed to bring together several measuringcables to one shielded cable .

If it is necessary to lengthen the measuring cable, then the terminals for the measuring cable must be separatefrom terminals with power. In general the same prinziple as for the cable is valid: the terminals must also beseparate depending from their function.

Heat development

The produced energie from the electronics must be undisturbed left the housing. It must be insure, that aircirculation is possible. All about the housing ( excluding the front plate ) must be a distance of min. 10 cm to otherobjects. To take off any cable on the top of the housing is not permissible. If several housings are installed, then the same principle is valid.

If fans are used, the distance can be reduced.One fan is necessary for two housings. The width of the fanmodule should be the width of the housing.

If the fan is only installed for air circulation, then it is important toknow, that the temperature in the housing can be increased.

If the inside air is exchanged with the air outside of the housing,then a dry air is necessary. For air circulation with the outside air please ask a manufacturerabout special components for installation in a panel cabinet.

Power supply

The installation of the cable for power supply 24 VDC/ 24 VAC must be laid star-shaped to each terminalconnector card QB 172 ( see B 407.4-11 D page 1 ).

Note : The dimension of the wire cross section for 24 VDC must be considering also the current for the solenoid valves

6. Requirements for commissioning: a) the meter must be correctly installed

b) the pipe must be completely filled with product

c) the power supply for meters and dosing control must be switched on

d) the flow velocity must be absolutely zero:

before starting the dosing/filling machine a zero point setting must be carried out;this is done by pressing key F7 and F2: the zero point procedure is carried out commonly for all converter cards/meters connected to the system. Upon successful completion, the green LED´s on the front panal of the MDS-30; MDS-49 and BGT-84 are off. If not refer to chapter 7., fault finding !

e) the start release unit of the filling machine must be connected:

This is connected to the start input of the master card DR-11 via its terminal adapter; a 24 VDC pulses of at least 10 ms is necessary.To check the operation ( follow-up the dosing procedure ) the operator terminal should be in position F6 ! If there are any problems refer to chapter 7.,fault finding.

7. Fault finding

a) zero point setting is not possible:

assumptions: pipe is completely filled with liquid,power supply is switched on

a1) power supply of the meter via the 3 LED´s of the terminal adapter card QB-173:

24 VAC for the meter coilsUpper LED is off check if 24 VAC is present

check fuses on terminal adapter QB-173

+ 15 VDC of converter card and pre- amplifiercentre LED is off check if 24 VDC is present

fault of converter card: replace!

- 15 VDC of converter card and pre.amplifierLower LED is off check if 24 VDC is present

fault of converter card : replace!

a2) reference voltage:

assumption: 24 VAC is present ( upper LED is on )prüfen: measure the reference voltage between the

brown wire and the shield ( terminal adapter QB-173 ); it should be 2,5 to 3,5 VAC!

if this voltage cannot be received:

check reference cable ( brown wire and shield ) on cable break or short-circuit

if reference cable is o.k.:

replace meter ( meter defect )

a3) set of automatic zero point :

for checking the function of the zero point setting circuitry ( part of the converter card UV-12 ) the white wire must be removed from the terminal. Then install a short connection between both terminals from the white wire and the shield on QB-173.Now press key F7 of the operator terminal and after F2 ( for " yes" ).

zero point setting successfull ? ( "Yes" means : green LED is off)if "no" : replace converter cardif "yes" : replace meter

a4) oscillation zero point:

check:

- the whole system ( piping, meter, valve) must completely be filled with product and free of gas- are the valves closed?- the conductivity of the product must be > 1 µS/cm- the flow velocity must be > 0.25 m/sec v (m/sec) = ( Q x 1.273,2 ) : DN2

Q (l/sec) = ( v x DN2 ) : 1.273,2

b) alternating/oscillating batch quantities:

b1) alternating/oscillating actual quantities( volume/weight of the receptacle):

check:

- does the liquid level of the tank decrease filling by filling by more than 5% of its previous value? The excess volume may differ from filling to filling. Refer to chapter 4, section a)!

- if the dosing time is < 0.5 sec the closing time of the valve influences the accuracy of the batch volume. The closing time of the valve must not excess 10% of the dosing time.

Refer to chapter 4., section c)c1)!

b2) altern./oscill. counter quantities ( see operator terminal key F6):

- if the real/true quantities ( appearing in the display ) differ by not more than +/- 1ml compared with the set quantities, but the contents of the receptacles do ( i.e. show bigger differences compared to the set quantities ) then the valve outlet is dripping ( varying from filling to filling ) When the valve closes the product must cease lowing instantly!

Check design/construction of the valve outlet !

c) Function of LED on Master card DR-11 and Counter/Valve card LS-23

These cards have 2 LED in front

red CPU

This LED is ON, if the CPU in the system stand still. In this case, the system is automatically restarted.

Check following, If this is not sucessfull :

a) EPROM installed ?b) CPU or EPROM correct installed in the socket ?c) Quartz for CPU --> OK

If a) to c) --> OK, change card

yellow no function for dosíng application

This LED is used for showing information for our serviceman. Several software version used this LED for indication e.g. the startinput.

How to take action

1. before first commissioning, and

2. when replacing components.--------------------------------------------------------------------------------------------------------------------------------------------------

1. before first commissioning

a. Activate batteries on cards DR- 11 and LS- 23:

The built- on batteries will store the set data in case of power failure.

Batteries on cards supplied from stock arede- activated to avoid discharge during storage.

To activate the batteries the jumpers must be brought in position " ON ".For jumper position see following drawings:

- card DR- 11: draw. No. 2- 81- 14816.4- card LS- 23: draw. No. 2- 81- 14821.4.

b. Set (key- in) system data into the LAUER terminal:

For correct function of the dosing system the following data must be set:

F1 number of dosing lines e. g. 1

F2 size (DN) of flowmeter e. g. 10 mm

F3 batch quantity e. g. 100 ml

F5 max. permissible dosing time e. g. 1000 ms

c. When using a PLC (instead of a LAUER terminal):

All telegrams, containing the system data, must be sent to the dosing system.

d. Fill dosing line with liquid.

e. Set zero point by pressing key F7.

Now the dosing system is ready for operation!-------------------------------------------------------------------------------------------------------------------------------- ------------------

2. when replacing components

If a card DR- 11 (or LS- 23) must be replaced by a new one, first activate thebattery on the new card by bringing the jumper in position " ON "; see above!If the dosing system contains further cards DR- 11 (or LS- 23), which must notbe replaced, pull their battery jumpers and bring them back to position " ON ".

Replacement of cards only when power supply had been switched- off!

So, all stored system data are erased!Key- in system data as described above.

Accuracy of Dosing Systems with Magnetic Flowmeters and ElectronicsSeries MID- MDS

-------------------------------------------------------------------------------------------------------------------------------- ----------------------

Introduction

Talking about accuracy of dosing systems series MID- MDS (also true for the system MID- NFD) means to talk about repeatability. The absolute accuracy, i. e. the difference between both the measured batch quantityand e. g. the weight, is not so important for dosing applications.All measuring (dosing) systems have inaccuracies. So, a dosing system consisting only of the magmeterand its dosing electronics (valve and nozzle/valve outlet are not included) has an absolute accuracy of

=< +/- 0.5 % of reading

within a velocity range of 0,5 to 10 m/sec.

This absolute (in-) accuracy is a constant quantity and can be eliminated by adjusting (changing) the presetvalue (batch quantity). With the new software (MDS) the calibration factor for each magmeter can bechanged individually and so the preset value (batch quantity) adjusted to an optimum.

But there is an additional uncertainty to be observed, the total repeatability R of the complete system:

Rtotal = repeatability of the complete systemRMDS = repeatability of the magmeter and dosing electronicsRvalve = repeatability of the dosing valveRnozzle = repeatability of the nozzle/valve outlet Rdensity = repeatability of the density of the liquid

RMDS = the repeatability of the magmeter and dosing electronics is=< 0.1 % of the batch quantity within a velocity range of 0,5 to 10 m/sec

Rvalve = the repeatability of the dosing valve is depending on the batch time; there is not yet any information known about the repeatability of e. g. GEMÜ valves.

According our experience with diaphragm valves: the repeatability is better than 1 % of the valve's delay time; the delay time of GEMÜ valves is approx. 70 millisec; afterthis time has gone the valve is closed. So, it is only important to know, which quantity passes the valve during this time!See two examples sheet 2!

Rnozzle = the repeatability of the nozzle(valve outlet) is very hard to be estimated; in general one must be sure , that always the same quantity passes the nozzle after the valve had been closed. No dripping is acceptable; if it is dripping, the number and the volume of the drops should be constant and cease quickly!

Rdensity = the influence of the density of the liquid is very important, too; it should be known as exact as possible; the liquid temperature should be kept as constant as possible during a machine shift to eliminate this influence!The density alteration of e. g. water is approx. 0.2 ml/degree centigrade.

RTOTAL = RMDS2 + RVALVE

Reference for determination of the meter size -------------------------------------------------------------------------------------------------------------------------------- ----------------------

It´s possible to fill up with one meter size a wide range of dosing quantities in the same time.

The table below shows, which meter size is recommended.

It shows the dosing quantity in relationship to the velocity in the meter pipe :

The velocity of 1 m/sec is ideal for high product care, accuracy and wear. If the velocity is higher, then the pressureshock increase if the valve is closing.. On the other hand, If the velocity is lower, then with several productsdeposits are possible..

Utilization for plastic pipes-------------------------------------------------------------------------------------------------------------------------------- ----------------------

It´s very important to know, that the dosing accuracy and the repeatablility are depending on the oscillation of theproduct in the pipe. A product oscillation is possible, if plastic pipes are installed within the product line. If the valveis closing, then the pressure increase and the plastic pipe works like a memory. If plastic pipes are required, thenthey must be metallcoated. A spiral from metal for reinforcement the plastic pipe is not adequate to guarantee therepeatability. The length of the plastic pipe must be as short as possible. Are the pipes are longer then 1 m, then a mechanicalsupport must be for prevent pipe oscillations, if pressure shocks are existing.
