Water Flow Sensor (FS300A) Humidity Interface: DigitalIntroduction: A G3 4" water flow sensor for providing more chooice of water flow sensors . Water flow sensor consists of 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
