● Create a device with measurement type "Flow".
● Start SIMATIC PDM. Create an assignment between the pressure to be measured
(measurement range) and the volume or mass flow to be recorded (working range), by
setting these parameters:

● To acquire the current flow, use "Function Block 1 – Analog Input". Create an assignment
between the measured flow value and the output value by setting these parameters:
