Oval gear meter model SRx-x is designed and developed for lubrication oil measurement in demanding industrial environments. This model is a positive displacement meter, which always shows the correct flow rate regardless of oil temperature or viscosity changes. These meters are compatible and part of our complete oil lubrication systems package. 

The flow meter consists of two elliptical gears which the flow rotates. A coil sensor or an inductive proximity sensor picks up the rotation. The pulse signal can be transferred to indicators, counters, or automation systems. The meter comes with flow adjustment valves and a five year warranty.
