Water flow sensor is the use of the Hall element to measure the Hall effect magnetic sensors of physical quantities. Water flow sensor mainly consists of copper body, water the rotor assembly, steady flow component and Hall sensors, installed in the water heater inlet side used to detect the size and water flow off.
