This device has two level indicators which work in harmony of a power switching relay. This relay is the one which connects the water pump to the mains power supply. If the system indicates that water level in the tank is Low, then the system turns on the power supply for the water pump. The pump remains till the system indicates the water level is low. Once the system indicates the water level as high and not low, the power to the water pump is switched off. It remains switched off till the water level is not again to the low level in the tank.
