High pressure, variable flow indicator with a graduated flow scale on the outer viewing sleeve and a indicator ring which is magnetically coupled to an internal piston
Utilises the technique of differential pressure across a piston which, as the flow increases, moves the piston against a calibrated spring
Can be installed in any plane without compromising accuracy and is supplied with a manufacturers instruction leaflet
Contains 2 independently adjustable microswitches housed in a metal enclosure with indicating flags showing the switch settings through the viewing window.
