Product Introduction

1/4 inch Water flow sensor YF-S402

Product Introduction:

Water flow sensor mainly consists of plastic valve body, water flow rotor assembly and hall sensor.

Installed flow sensor to the inlet end of the water heater, to detect the rate of inlet water flow. When water passes through the flow rotor assembly,the magnetic rotor rotates and the rotating speed changes with the flow rate. Hall sensor outputs the corresponding pulse and feed back to the controller, which determines the flow range of water and regulates.

Product Feature:

1. Product is with light and small structure, easy to install.

2. The impeller is inlaid with stainless steel beads for permanent wear resistance.

3. The sealing ring adopts the structure of upper and lower force and never leak.

4. Hall element is imported from Germany and sealed with filling glue to prevent water intake and never aging.

5. All raw materials meet ROSH testing standards
