Applications

Applications of 3/4 inch Magnetic Water Flow Switch

Tips: Internal structure of magnetic water flow switch

A piston with a permanent magnet is arranged on the fluid channel inside the water flow switch housing. When the piston is pushed by the pressure difference caused by the fluid flow, the magnetic piston lead the sealing reed switch inside the device to operate. The diameter of the piston determines the starting flow rate. When the flow decreases, the stainless steel spring pushes the piston back into place. When the reed switch is actuated, it can transmit alarm or instruction remotely, or it can be integrated into the automatic control system. In addition, set the upper or lower limit for the flow switch, when the flow reaches the limit value, the flow switch will send a signal or alarm, and the system will run or stop. Flow switches are usually used in systems that require flow.

Nice magnetic water flow switch and no leaking!

This magnetic water flow switch is much better quality than the cheap ones. I bought the flow rate of 15L/min. Easy to operate and install. The switch responds quickly and has a small size, which is both space-saving and appealing. Nothing has been wrong with external or internal leakage. I am going to buy a few more.

Great magnetic water flow switch

I used magnetic water flow switch this on my solar water heater. I followed the steps in the manual to install the switch and it was set up quickly. After that I tested the operation of my water heater and the water came out and shut off very quickly. The water shut off was pretty tight and it did not even show a drip. I love this flow switch so much.
