Flow Indicator/ Switch NJ / NJV Scale for various viscosities or viscosity stabilised from 30 to 200 mm²/s Also for dark or dirty media Robust construction Characteristics Mechanical flow meter with spring-supported piston for fluid media. The measured value is transferred to a display ring via a magnetic coupling. Because of this separation, the display cannot become dirty. Robust construction in brass or stainless steel.
