he Flow Instruments covers instruments like Mechanical Flow Meters, Mechanical Flow Gauges, Digital Flow Rate Indicators, Digital Flow Totalizers, Digital Flow Meters, Flow Transmitters, Flow Switches etc. Except the Mechanical Flow Meters NK Instruments Pvt. Ltd. have all other type for Flow Instruments.

We have Indicating type Flow Switches which operates like Rota meter and it has a field settable switch, which will operate as soon as the flow passing through this switch is not within the set limits. Series : WFS series Service : Any free flowing liquid or gases Max. Particle size should not be more than 150 microns Mounting : Vertical or, Horizontal Process connection : 1/4', 3/8', 1/2' or, 1” Flow set point : single or, two nos. Field Settable Electrical connection : 500 mm long two core wire Wetted Parts : SS 304 / Brass & Polycarbonate, for 25 & 30 mm Borosilicate Glass instead of Polycarbonate Switch type : SPST (NO) Reed Switch (10 VA 230 VAC) Switch setting : Adjustable Repeatability : Better than +/- 1% Accuracy : +/-2.0 % Scale Tolerance : +/- 5% of Full Scale Max. Working Pressure : 10 bar Max. Working Temperature : 120 degree C
