Product Description

KRACHT VC0.04F1PS/71 Volumetric Flow Meter

The KRACHT VC0.04F1PS/71 is a high-precision gear-type volumetric flow meter designed for accurately measuring the flow rate of various liquids, including oils and other viscous fluids. It operates on the principle of positive displacement, where rotating gears trap and transfer known volumes of fluid, providing highly accurate measurements independent of viscosity fluctuations within its operating range. This model features a robust cast iron body and FKM seals, making it suitable for demanding industrial environments. The integrated /71 inductive pulse generator provides a reliable square wave output signal proportional to the flow rate.
