How to install a constant pressure water pump

Working principle ↓↓↓↓↓↓↓
1. The VFD drives the water pump, and the pressure sensor/transmitter feeds back the
pressure signal to the VFD to form a closed loop system.
2. When the water pipe pressure is less than the set value, the VFD wakes up and starts
pumping water.
3. When the pressure does not reach the set target, the operating frequency will continue
to increase to the rated frequency of the pump.
4. When the pressure is greater than the set pressure, the operating frequency will
decrease.
5. When the pressure is greater than the sleep pressure, the frequency decreases to
the sleep frequency for a period of time, and then stops pumping water.
6. When the pressure is lower than the wake-up pressure, the pump starts to run again.
