This product is carefully developed according to the actual needs of family factories pumping. This product is based on the detection of water level (water tower) to control large current relay to realize the control of pumping water. The features of small size, simple connection, low power consumption, large switching capacity, strong anti-interference ability, high functional stability, etc.. To achieve stable pool (water tower) is automatically opened when the water pump (solenoid valve) pumping water, the pump automatically stops the water is full (solenoid valve).
