Kelco CR22 20mm Low Flow Chemical Resistant Microflow Switch

The CR22 microflow switch operates on the displaced piston principle. Process liquid passing upwards through the switch lifts a precision piston. Every time the piston is lifted a magnet sealed inside it actuates an external reed switch.

The reed switch provides a signal indicating flow. The CR22 can be setup as a normally on or a normally off switch that responds either to flow, or to loss of flow.
