DESCRIPTION
The CR22 microflow switch operates on the displaced piston principle. Process liquid passing 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 fl ow. The CR22 can be setup as a normally on or a normally off switch that
responds either to flow, or to loss of flow.
