Oval gear monitors
Oval type flow meters are a complete flow measurement and monitoring system for re-circulating oil systems.
The method of measurement is based on the rotation of special oval designed gears – the speed of which changes in proportion to the flow of oil through the meter. This gives a visual indication of the flow rate through the transparent cover and also sends electrical pulse signals to an electronic monitor or PLC to provide actual flow figures.
This also provides information to allow either low or high flow monitoring to be provided.
Measurement is independent of viscosity and therefore a real flow will be indicated throughout the temperature range.
Pressure drop through the flow meter is relatively low.
The flow meter is designed to pass a small flow even if the gears are prevented from turning due to solid particles contained in the oil. This prevents complete starvation of oil to bearings etc.
