Industrial Flow Indicators - Flowline 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. Features and Benefits • 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 calibrated Maximum operating temperature 90°C Calibration Water SG 1.0 at 20°C Scale Reading 10% FS (min) Accuracy ±5% Repeatability ±1% Body Brass to BS2874 Wetted parts Magnet Alcomax, PTFE coated Non-wetted Parts Seal Viton Retainer Gland Brass to BS2874 CZ 121 M plated with electroless nickel Indicator Ring Mild steel plated with electroless nickel
