## Description

Main application:Magnetic Water Flow Switch adopts a Magnetic Reed Switch and a movable magnet which is fixed inside the water pipe. When water runs through the pipe part, the magnet will detect the water flow, and the magnet is shoved to one side by the flow. This then attracts the conductive strip which gets pulled down and makes contact, which completes the circuit and activates whatever electrical device you have attached to itSpecifications:Thread type: 3/4" BSP Male ThreadIt is fit in NPT Thread if you connect them with teflonOperation voltage: 0-220V(AC or DC)Flow range: 1-30L/minWorking temperature: 1-120℃Mini start water pressure: 0.02MpaMax working pressure: 1.75 MPaMax loading power: 50WWorking current: 0-2AResponse time: 0.2SMaterial: BrassMale Thread External Diameter: 25.85mm(1.0 inch)Tube Length: 60mm(2.36 inch)Cable Length: 29cm(11.41 inch)Size: 60mm*30mm*30mm(L*W*H)Please Note:Don't forget to mark which way the old flow switch arrow is pointing so you can install exactly the same.Package Include:Brass Flow Switch x 1

Review: bueno
Review: Does the job. - It works well. I had to buy two 3/4” G Thread (BSP) Female to 3/4” NPT Male Connector (like ASIN B0B74F451Y). It is very difficult to get the connection not to leak, even with a lot of Plumber's Tape between the flow sensor and the BSP to NPT adaptor. However, I inserted a hose washer in between and did not need Plumber's Tape. No leaks. See photo of the hose washer. Use this one , not the orange type because the orange will expand inside and reduce the flow. I read here that some people do not use BSP to NPT adaptor and use a lot of Plumber's Tape. So, a hose washer, may be a solution for that too.

### ⭐ Flow switch doesn’t return after water stops flowing
*by R***C on January 24, 2024*

This is the second flow switch I bought through Amazon, two different styles , first one outer casing was defective had a pin hole, this one I still have hooked up, it is controlling a recirculating pump for tankless water heater running through a relay so pump only runs when water starts flowing. The problem is that the NO contact does return to the open position , allowing the pump to keep running, if I tap on it with a screw driver it returns to open and turns off the pump. Two for two 🤔🥴
