SRZ 40 ST

Helical Flow Meters in Standard Design for high-viscosity and abrasiv media

The SRZ ST helical flow meter series (ST for standard version) are flow-measuring devices that are used mainly in highly viscous, abrasive, filled as well as lubrication and non-lubrication media.

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.
