High-pressure, variable flow indicators with a graduated flow scale on the outer viewing sleeve and an indicator ring which is magnetically coupled to an internal piston. All utilise the technique of differential pressure across a piston which, as the flow increases, moves the piston against a calibrated spring. Can be installed on any plane.• Pressures up to 350 bar,• Flows up to 360 L\/min,• Accuracy ±5% FSD,• Repeatability ±1% FSD,• Relatively insensitive to viscosity changes,• Direct reading,• Oil or water calibratedMedia Monitored = LiquidDevice Type = Variable AreaMinimum Flow Rate = 1 L\/minMaximum Flow Rate = 9 L\/minPipe Diameter Range = 1\/4 inConnection Type = 1\/4 BSPMaterial = BrassMaximum Operating Temperature = +90°CSeries = Flowline
