Helical Screw Flow Meter RS type

Helical Screw Flow Meter RS type

RS flow meters measure the flow rate based on the screw pump principle. The newly developed rotor profiles ensure a low-resistance, high-precision measurement while gently transporting the measuring medium.VSE optimized material and technology in the bearing area.

The combined radial / axial slide bearing is shielded behind bearing brackets shaped to be flow-optimized. The bearings are made from tungsten carbide and, the first time in positive displacement flow meter, also made from silicium carbide (SSiC).

A sensor module was developed that enhances the functionality of the RS flow meter significantly. The sensor itself features two GMR bridges (sin/cos) and is housed in a removable stainless steel cartridge case together with a signal conditioning and amplifier unit.

The downstream electronics unit features a high-resolution sin / cos-interpolator. Among others, the device features a programmable signal filter, which is able to offset unwanted, negative pulse sequences and detects and saves values that exceed the indicated flow and temperature values. A separate directional signal is available for 1-channel evaluations.
