10. Enter the desired name for the block (optional).
Factory setting: TRANSDUCER_FLOW_ xxxxxxxxxxx
11. Open the Transducer Block "Flow".
12. Now configure the device-specific parameters relevant for your application.
– Enabling code in "Un-/Locking - Access Code" parameter Transducer Block "Flow"
Page 89 (factory setting = 72)
– Select state of aggregation of the fluid Transducer Block "Flow" "Process Param.
Application" Page 93
Configuration examples for commissioning:
Example 1 (volumetric unit)
You want to measure the flow of water.
The flow should be displayed in the volume flow unit m³/h.
The following settings must be made when commissioning is performed:
Example 2 (mass unit)
You want to measure overheated steam with a constant temperature of 200 °C and a constant
pressure of 12 bar. According to IAPWS-IF97, the density at operating conditions is 5.91 kg/m³.
(IAPWS = International Association of Process Water and Steam). The flow should be displayed in
the mass flow unit kg/h.
The following settings must be made when commissioning is performed:
Example 3 (corrected volume unit)
You want to measure compressed air with a constant temperature of 60 °C and a constant pressure
of 3 bar. The density at operating conditions is 3.14 kg/m³. The density of air at reference operating
conditions (0 °C, 1013 mbar) is 1.2936 kg/m³. The flow should be displayed in the corrected
volume flow unit Nm³/h.
