Magnetic water flow switch 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.

Applications

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.
