The water flow sensor is mainly composed by plastic valve body、rotor assembly and hall sensor.
It is installed at the inlet end of various water equipment and it used to detect the inlet flow rate. When water passing through the rotor assembly, the magnetic rotor rotates and the rotational speed changes according to the flow rate. The hall sensor output the corresponding pulse signal , feedback to the controller.
The main function of the controller is to measure cumulative flow and instantaneous flow ; single quantitative and total quantitative analysis, and water temperature detection.
