●Application :Automatic water supply system for household water tower,Aquarium fish tank water changing system,Automatic filling of water tower,Automatic pumping of water tower
●Working Principle : Water level rise: When the water level is lower than the "low water level", the pump starts to supply water to the water tower; when the water level is higher than the "high water level", the pump stops water supply. Water level drop: When the water level is lower than the "high water level", the pump does not work and the water level continues to drop. When the water level falls below the "low water level", the pump starts to supply water to the water tower.
●The NO and NC ports of the relay are connected for two purposes: the water pump is connected to the COM NO port to automatically pump water from the water tower. The water pump is connected to the automatic water injection tower at the COM NC port.
