How to fill in the Flow Data Sheet

Not every information on the Flow Data Sheet is of the same importance but all fields marked * has to be completed. The order cannot be processed and production of the device cannot be started as long as those points are not clearly clarified.

These fields are optional or ‘nice to have’. However, it must be ensured that the Flow Data Sheet meets the corresponding instrument order during production. Filling-in the order no., pos. and order code may help to avoid mistakes.

How to fill in the Flow Data Sheet Important: First select the fluid type (steam, liquid or gas) and then fill-in the fluid name or chemical formula (except steam). Depending on your entry more information may be required.

Clearly defined liquids and gases like oxygen, nitrogen, pure water or ethanol do not require further entries. All necessary information about these data are easily accessible in the relevant literature. Mixtures (e.g. natural gas) or brand names (e.g. Shell motor oil) do not provide sufficient information for the calculation. More information is required.

How to fill in the Flow Data Sheet Density: The density is an essential input value of the flow calculation. This field must be completed in case of mixtures and brand names.

The influence of the viscosity value on the calculation is normally very small and negligible. The Reynolds No. is a function of the viscosity. This may be a limiting factor for the measurement especially with highly viscous liquids.

Standard orifice: Re >= 5000 according to ISO5167 Pitot tubes: Re >= 3000 depending on manufacturer ¼ circle nozzle: Re >= 500 according to ISA2041

How to fill in the Flow Data Sheet Rel. humidity in a pure gas means to have a mixture of the mentioned gas and water vapour. The density of the mixture depends on the absolute amount of water in the gas, which is a function of the relative humidity and the temperature. In most cases the influence is small.E.G.: 70% rel humidity @ 86°F equals a water vapour pressure of 12”H2O. The normal density of air will drop 1,278 kg/Nm³ (dry air 1,293kg/Nm³)

Mixing up reference conditions is a frequent source of mistakes. The unit entered for the density must match the selection of the reference condtions.E.g. Selected condition ‘Normal’ -> Density given in kg/Nm³Density of air is ‘normally’ 1,293 kg/Nm³, but approx. 12,9 kg/m³ @ 147psi/32°F operating conditions.

1. Gases usually do have very low viscosity values. The risk of being limited by the Reynolds-No. is quite low.

2. The Compressibility factor does have an influence on the density especially at high pressure. If the density is given at normal or standard conditions this may have a quite big impact on the calculation result. If this value is not available the calculation will be done with the factor set to 1 or in case of clear defined mixtures with a factor estimated from the ingredients.

3. The influence of the specific heat ratio on the calculation is small and usually negligible.

4. Very often customers are not able to provide these values.

1. The calculation can only be done for one single process condition (operating condition). 2. Changing process conditions must be compensated using a flow computer3. The minimum flow rate is mainly depending on the resulting dp and the Reynolds No.

A typical measurement dynamic (Turndown) is 6:1. TDs > 12:1 require split range configurations with more than one dP-transmitter.

4. Don’t forget to clearly mark if the pressure values are relative or absolute.5. The maximum process pressure/temperature will not be taken into account for the

application but is important for the correct selection of the pressure rating. PCM will not check the selected pressure rating (order code) according to entries in these fields.

Flow Data Fields marked (a) will be used for the calculation of the primary element.The correct selection of the pressure rating is under the responsibility of the end user.

Also for the requested flow rates it is essential (only for gases) to be sure about the reference conditions. The flow unit must match the selected reference condition.

The selected material of instruments with welding sockets/flanges (DPP10/50 - pitot tubes, DPO12/52 - flange tappings) must match the pipe material. High temperature applications often require special materials. Highly abrasive or corrosive media may require special materials. Many special materials are available as TSP versions.

Why is the internal diameter so important?Orifice: The relevant standards do not allow sudden diameter changes

within the straight inlet and outlet lengths. According to ISO5167/VDI2040 the pipe diameter enlargement (or

contraction) has to be done with a cone angle < 8° in a distance of at least 2D (D= internal diameter) upstream and downstream.

Deviation- and uncertainty calculations (similar to E+H Prowirl) are not allowed.

The calculation is based on the exact internal diameter. Wrong dimensions will cause huge errors.

Pitot tube:Diameter increase of 5% (e.g. from 6,0 to 6,3”) -> increase of cross section area of the pipe: 10,25%-> decrease of velocity (at the same flowrate): 10,25%-> decrease of dp (due to square root function): 21,55%

Mechanical problems due to wrong pipe dimension:Orifice: Orifice may not fit between flange bolts Orifice flange possibly can not be welded due to different

diameter and wall thickness.Pitot tube: Pipe diameter bigger

Tap holes not symmetrical distributed -> measurement error 3…10%

Pipe diameter smaller Cutting ring version: Tap hole to close to the pipe wall or inside

welding sockets -> measurement error up to 70% (normally too low)

Rectangular ducts: Usually the pitot tube should be mounted parallel to the longer

side of the duct. Installation parallel to short side of the duct may be advantageous

depending on the upstream or downstream situation. Applicator calculates with a virtual diameter for round pipes. Pitot tube nominal length has to be selected according to the

inner dimension and wall thickness of the selected duct side E.g rectangular duct 25,5” x 16” (height x width)
