Vacon 100 flow Applications Manual

The sensor is put in position 1. The pressure in the pipe stays constant when there is no flow.
But with flow, the pressure decreases farther in the pipe. To compensate for this, lift the
setpoint as the flow increases. Then the output frequency makes an estimate of the flow, and
the setpoint increases linearly with the flow.

10.14.8 SOFT FILL
The Soft fill function is used to move the process to a set level at a slow speed before the PID
controller starts to control. If the process does not go to the set level during the timeout, a
fault shows.
You can use the function to fill an empty pipe slowly and prevent strong currents of water
that could break the pipe.
