Abstract
A fluid flow meter is described, that includes intermeshing gears that may rotate synchronously. The fluid flow meter may produce a pulsed output that can be normalized to suitable values according to a method of normalizing input pulses generated in response to the rotation of gears. A volume counter can be incremented by an amount equal to a volume per input pulse each time an input pulse is generated. When the volume counter exceeds a first reference volume, a normalized output pulse can be generated until the volume counter exceeds a second reference volume.
