P3.13.7.1 ENABLE COMPENSATION FOR SETPOINT 1 (ID 1189)
P3.13.7.2 SETPOINT 1 MAX COMPENSATION (ID 1190)
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.
