What does pressure sensor do for VFD inverter constant pressure pump?

A variable frequency drive (VFD) / variable speed drive (VSD) Inverter Constant Pressure Booster Pump needs a pressure sensor to be mounted on the outlet to measure the operating pressure and help the pump to determine to run or stop, and the running speed. The VFD / VSD Inverter Constant Pressure Booster Pump Manager will be set to keep the water pressure of the pump constant, no matter what flow is produced from the pump.
