Product Description:OOTD Water Flow Sensor includes plastic housing/brass body, water rotor and hall sensor, PCB electronics board. Working efficiency: when the water flows through the impeller, the impeller is coiled. Its velocity varies with different flow velocity. Then the magnetic rotor reacts to the hall sensor, the hall sensor outputs the corresponding pulse signal. The flow sensor is suitable for detecting the flow in the water dispenser or coffee maker . Specification: Material: BrassType: Hall Flow Meter Mounting Position: Horizontal and Vertical Application: Boiler, Broiler and Heat Pump. . Etc.
