ABSTRACT:
The present invention relates to a system and a method for compensating for predicted meter drift is a positive displacement meter comprising a pulser connected to the meter for generating a pulse stream indicative of a current volume delivered through the meter; and a pulse processor in electronic communication with the pulse generator. The pulse processor adds or subtracts pulses indicative of the inverse of the predicted meter drift to or from the pulse stream to create a corrected pulse stream. The amount of inverse applied is determined by the value of the current cumulative volume passed by the meter.
