description A fluid flow meter is described, that includes intermeshing gears that rotate synchronously. The fluid flow meter has a nominal operating range between a maximum volumetric flow rate and a minimum volumetric flow rate. The flow meter has a flow sensor to produce a pulsed output and a controller operatively coupled to a data storage medium. The controller can receive detection signal from the flow sensor to generate input pulses and determine an input pulse frequency. The controller can determine whether the fluid flow meter is operating outside the nominal operating range and apply a correction function to input pulses to generate linearized output pulses. The controller may generate the correction function based on the input pulse frequency and a predetermined pulse frequency; or based on the time interval between input pulses and a predetermined interval between input pulses; or based on a generic calibration of the fluid flow meter.
