YF-S403 5-18V Water Flow Sensor Flowmeter G3/4 1-30L/Min
YFS403 5-18V Water Flow Sensor is mainly a It consists of a plastic valve, water flow rotor assembly and a Holzer sensor. With the rotation of the magnetic rotor and the change of flow rate, the rotation speed changes, and the output of the Holzer sensor corresponds to the pulse signal by the controller, feedback to the controller to determine the size of the water flow. When water passes through the flow rotor assembly, the magnetic rotor will rotate and the Speed will change as the flow changes. The Hall current sensor output corresponds to the pulse signal and feedback to the controller, then the controller controls the flow. It can be used for water heaters, credit card machines, water vending machines, flow measurement devices.
This model also includes a temperature sensor. In this way, you can read the temperature of the liquid passing through the engine.
