Product Overview



G1/2" DN15 Magnetic Brass Flow Switch

Product Description


Product Description


Working theory:


The magnetic water flow switch is a device used to sense the water flow rate and switch on/off the flow in the pipe. There is a magnetic element in the flow switch. When liquid flow rate reaches the specified value, the magnetic element will be pushed closed to the sensor inside the switch, connect the circuit, and get signal transmitted.


Product Application

This magnetic water flow switch  can be used to monitor liquid flow rate in water machine, water heater, coffee machine, vending machine, water meter, medical testing machine and the like. They are widely applied in industrial equipment, agricultural equipment and household electrical appliances in the future.
