SRZ ST Series Kem Kuppers Helical Flow Meters

The SRZ ST helical flow meter series (tungsten carbide sleeve bearing design) are flow-measuring devices that are used mainly in high-viscosity, abrasive, filled as well as lubrication and non-lubrication media. These include polyurethane, polymers and viscous products, as well as all kinds of greases and oils.

Thanks to its concept, temperature fluctuations and the resulting change in the viscosity of the medium only marginally affect the measuring accuracy of the SRZ ST. This makes it especially well suited for use in test stands and for measurements with changing application conditions. Furthermore, the helical flow meter is distinguished by a wide measuring range, low shear stress of the medium to be measured and low loss of pressure.

Only high-grade steels that even withstand corrosive liquids are used in the production of helical flow meters. Combined with the use of tungsten carbide bearings, the SRZ ST guarantees optimum measurement accuracy and a long service life even under the toughest application conditions.

Short response times, very dynamic performance and high measurement accuracy ensure accurate regulation and control of flow rates in demanding applications.

For applications in hazardous areas, we offer intrinsically safe sensors and amplifiers with Ex protection in accordance with ATEX, IECEx, CSA and other standards. Additional certifications such as EAC (TR-CU) are available.
