Product Details

MR-B678-1 liquid flow switch

Introduction

Flow switch consists of magnetic core, rotating impeller, external casing and reed switch. Flow through the sensor activates the magnetic core to trigger switch action, with signal output.

Features

Imported components of the magnetic switch, sample working principles, and highly reliable, cheaper price.

Applications

It is used in the control of water circulation, water charging and discharging, water heating, water pump switch

on and off of solenoid valve, or powering on and off of water discharging for electric water heater, solar energy

water heater, air condition and other water systems.
