MAX COMPENSATION
The sensor is placed in Position 1. The pressure in the pipe will remain constant when we have
no flow. However, with flow, the pressure will drop farther down in the pipe. This can be com-
pensated by raising the setpoint as the flow increases. In this case, the flow is estimated by the
output frequency and the setpoint is linearly increased with the flow as in the figure below.
