Measuring principle
Oval wheel meters are positive displacement flow
meters. The measuring element consists of two
precision oval wheels, driven by the fluid. Each
revolution of the oval wheels displaces a precisely
known volume of liquid through the meter.

The number of revolutions therefore is directly
proportional to the measured volume.
