Helical Flow Meters with Ball Bearing (SRZ KL)

for high-viscosity, not abrasiv media

The series SRZ KL flowmeter (KL for ball bearing version) is a volume flow meter intended primarily for lubricating, non-abrasive fluid applications. 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 KL. This fact, the high measuring accuracy, and the wide measuring span make this the ideal flowmeter in test stands and for applications with fluctuating operating conditions.
