Description

VSE RS Helical Screw Flow Meter is the ideal solution for precise flow measurement. Thanks to various bearings, tolerances, materials, coatings, electronics, and resolutions, VSE finds the right solution for challenging applications. An optional high-temperature pick-up system means that the RS can also be used in extreme temperature zones.

VSE RS Helical Screw Flow Meter Descriptions

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 digitized, processed, and output in the sensor module.
