The Principle of all kinds of Flow Switches

1. Working principle of rotor type water flow switch
The rotor type water flow switch, also known as the rotameter, can detect the water flow in the closed water pipe.
The rotor type water flow switch is composed of tapered pipe, magnetic rotor, stop and magnetic switch.



2. Working principle of piston type water flow switch
The piston type water flow switch is composed of a housing, a magnetic piston, a magnetic switch and a spring.



3. Working principle of flap type water flow switch
Turnover plate water flow switch is composed of shell, turnover plate and proximity switch.

4. Working principle of target Paddle water flow switch.



5. Working principle of differential pressure water flow switch.

Differential pressure water flow switch consists of differential pressure plate, diaphragm, push rod, venturi and return spring.
