Measuring Principle
Oval wheel meters are direct volumetric meters. The measuring
element consists of two meshing precision oval wheels which are driven
by the liquid. Therefore, each revolution of the oval wheels transports
an exact quantity of liquid, defined by the geometry of the measuring
chamber, through the meter.

The number of revolutions is directly proportional to the flow quantity.
These are scanned by a pulse pick-up.

Applications, e.g. for measuring the volume and
consumption of lubricating oil, mineral oil, fuel oil
and hydraulic oil, of diesel in power units, burners
and engines, of greases, paints, oil circuits and
oil treatment plants, etc.
The device is suitable for industrial application
due to its robustness and excellent accuracy. The
oval wheel axles are pivoted on both sides, a
feature which enables this meter to function
perfectly during pressure surges, short overloads
or with high viscosities.
