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.
