Introduction

 

The water flow sensor is mainly composed of plastic valve body, water flow rot assembly and Hall sensor.

 

It is installed at the water heater in-water terminal, used to detect in-water flow, when the water through the water flow rotor assembly, magnetic rotor rotation and speed changes with the flow rate, Hall sensor output corresponding pulse signal, feedback to the controller, by the controller to determine the size of the water flow, control.
