YF-S403 3/4" Water Flow Hall Sensor

YF-S403 3/4" Hall effect Based Flow Sensor

Water flow sensor is mainly consists of plastic valve body, rotor assembly and hall current sensor. This flow sensor can be used for accurate flow measurement. It is installed in the hot water inlet end for detecting water flow. When water through the flow rotor assembly, magnetic rotor will rotate and Speed will change as the flow change. Hall current sensor output corresponding pulse signal and feedback to controller, then the controller will control the flow. Can be used for water heaters, credit card machines, water vending machine, flow measurement device.
