The YFS403 5-18V Water Flow Sensor mainly consists of a plastic valve, water flow rotor assembly, and a Holzer sensor. The rotation of the magnetic rotor and the rotating speed change with the change of the flow rate, and the output of the Holzer sensor is corresponding to the pulse Signal, feedback to the controller, by the controller to determine the size of the water flow, control.
It is installed in the hot water inlet end for detecting water flow. When water through the flow rotor assembly, the magnetic rotor will rotate and Speed will change as the flow change. Hall current sensor output corresponding pulse signal and feedback to the controller, then the controller will control the flow. Can be used for water heaters, credit card machines, water vending machine, flow measurement device.
