Working Principle of the Oval Gear Flow Meter

The measurement process begins when fluid enters the flow meter. The pressure difference between the inlet and outlet drives a pair of oval gears to rotate.

As they turn, the fixed crescent-shaped volume between the gears and the housing is sequentially filled and emptied. Each complete rotation discharges a precise, fixed volume of fluid, enabling highly accurate volumetric flow measurement.
