A flow switch is a mechanical instrument that is used to control the flow of air, steam or liquid. Flow switches work by sending trip signals to another device (a pump for example) within the system, telling it to shut off or to turn on, which will further protect it from damage and for cooling circuit protection.


Flow switches are used for the display and monitoring of the flow of liquid and gaseous media. The instruments feature a high switching accuracy and functional like Switzer flow switch for example.

Flow switches are mechanical devices used in controlling the flow of air, steam, or liquid. A flow switch operates by conveying a trip motion (relay, reed switch, paddle) to another machine within the system, usually a pump. The trip signal will indicate to the pump to turn on or turn off. It is necessary to provide damage protection and circuit cooling or adjust flow rates that are too high or too low.
