As shown in the figure, the circuit uses electric contact pressure gauge and inverter ( Japan Sanken 22kVA) to control the speed of on pump and realize water supply with constant pressure. The power supply terminal R , S , T of U can connect with switch, AC contactor. SP is installed in main road which is near the pump outlet with little effect from the amount of water.
