RS Series helical screw PD flow meters

Helical screw sensors RS Series

The VSE RS helical screw flow meters measure the flow rate based on the screw pump principle. The measurement of the volume flow with the RS innovative rotor profiles offers significant benefits such as a low-resistance, highly precise and pulsation-free measurement with minimal shear, lowest pressure losses as well as highest functionality based on intelligent sensor technology. Whether with low viscosity oil or with thick resin, the RS flow meters are the ultimate solution for precision flow measurement. With countless of possible options for size bearings, tolerances, materials, coatings, electronics, resolution & ATEX, there is an option to suit even the most demanding applications.
