VSE RS Helical Screw Flow Meter

VSE RS helical screw flow meters impress with a low-resistance, pulsation-free and high-precision measurement of the fluid with minimal shear, low pressure losses and maximum functionality thanks to intelligent sensor technology.

Whether low viscosity oil or viscous resin – RS flow meters are the ideal solution for precise flow measurement. Thanks to various bearings, tolerances, materials, coatings, electronics and resolutions, VSE finds the right solution also for challenging applications. An optional high temperature pick-up system means that the RS can also be used in extreme temperature zones.

RS flow meters measure the flow rate based on the screw pump principle. A pair of rotors fitted precisely into the housing constitutes the measuring element. An integrated gear and non-contact signal pick-up system detects the rotations of the measuring element and converts them to digital pulses. Together with the housing walls, the rotor edges form closed measuring chambers in which the fluid is transported from the inlet to the outlet side. The fluid volume put through within one main rotor rotation is the rotation volume, which is divided by the sensing gear and digitised, processed and output in the sensor module.
