Depending on whether you want to measure a height, a volume, or a mass, set the following
values.
Height measurement
To select height measurement, proceed as follows:
● Start SIMATIC PDM. Create an assignment between the pressure to be measured
(measurement range) and the fill level to be recorded (working range), by setting these
parameters:
