Helical Flow Meters (SRZ) are volumetric flow meters that are mainly used for highly viscous, abrasive, filled as well as lubricating and non-lubricating media. Polyurethane, polymers and viscous materials, but also greases and oils of all kinds are among them. Thanks to its design, temperature fluctuations and the resulting change in medium viscosity have only a marginal effect on measurement accuracy. Only high-quality stainless steels that can withstand even corrosive media are used to manufacture the spindle flowmeters. Short response times, very dynamic behavior and high measuring accuracy ensure precise regulation and control of volume flows within demanding applications.
