The SRZ ST spiral flow meter series (ST for standard version) are flow meters used primarily in highly viscous, abrasive, filled and lubricating or non-lubricating media. Thanks to its concept, temperature fluctuations and the resulting change in the viscosity of the medium have only a minor influence on the measurement accuracy of the SRZ ST. This makes it particularly suitable for use in test setups and for measurements with varying application conditions.
