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.Media Monitored = LiquidDevice Type = Boxed Two-SwitchMinimum Flow Rate = 10 L\/minMaximum Flow Rate = 110 L\/minSupply Voltage = 250 V acPipe Diameter Range = 3\/4 inMaximum Pressure = 350barMaterial = Stainless SteelMinimum Operating Temperature = -20°CMaximum Operating Temperature = +90°C
