In an OVAL flowmeter, two oval gears in the metering chamber revolve by the energy of the fluid. The volume of the crescent shaped spaces surrounded by the metering chamber and the two gears is a known value. When the gears revolve one turn, the cresent spaces are discharged four times. Therefore, by measuring the number of gear revolution, the volume of the fluid passing through the flowmeter can be measured. The unit of flow is volume.
