Elecrow 1/2-In Water Flow Sensor

Description Elecrow 1/2-In Water Flow Sensor Has a magnetic core and a rotation impeller The hall-effect sensor outputs the corresponding pulse signals Detects flow in water dispenser or coffee machine The Elecrow 1/2-In Water Flow Sensor consists of a magnetic core, rotating impeller, external casing and sensor, and a hall-effect sensor. When water flows through the rotor, rotor rolls, it activates the magnetic core to trigger switch action speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signals, users can get the flow speed via detecting the pulse. It is suitable to detect flow in water dispenser or coffee machine.
