For volume and mass flow measurements, the device uses adjustable square root functions.
For volume measurement, the device uses the tank characteristic curves for various vessel
geometries.
In the
"Customized characteristic curve" application, enter the breakpoints of the characteristic
curve using remote operation (e.g. SIMATIC PDM).
The set application acts directly on the current output:
