Senseca NJVM2-015GM010 Flow Indicator / Switch

Flow Indicator/ Switch NJ / NJVInstallation locationStandard: Vertical inwards flow from bottom to top. Further installation positions are possible; the installation position affects theswitching point and indication range.Ranges Details in the table correspond to horizontal inwards flow with increasing flow rate.Standard NJ G G 1/4 G 3/8Display range l/min H2O 2 - 104 - 20 2 - 10 4 - 20 10 - 40 G 3/4 2 - 10 4 - 20 10 - 40 G1 2 - 10 4 - 2010 - 40 20 - 80 Special ranges are available.G 1/2● Scale for various viscosities or viscosity stabilised from 30 to 200 mm²/s● Also for dark or dirty media ● Robust constructionCharacteristics 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 becomedirty.
