The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly, and a Hall sensor. It is installed at the water inlet end of the water heater to detect the influent flow rate as it passes through the water flow rotor assembly. The magnetic rotor rotates and the rotational speed changes with the flow rate and the Hall sensor outputs a corresponding pulse. The signal is fed back to the controller, and the controller determines the magnitude of the water flow and performs regulation.

FS200A YF-G21 Water Flow Sensor valve can measure the flow of liquid in the range of  1 to 30 Liter per minute. This valve operates on 5 to 18V DC voltage with a very minimum current requirement which is between 10 to 15 mA.
