ABSTRACT:
A pulse production interval measurement module (or temporal reconciliation module) for preferred use with a computational flowmeter to thereby temporally reconcile or time shift flowmeter output produced by a volume of fluid flow through the computational flowmeter with the start and stop times of the flow of a calibrated fluid volume through a prover. The pulse production interval measurement module may be implemented with software and/or hardware and operate on stored data or real time or near real time measurements. Timing signals are sampled or collected with respect to one or more measurement elements within the computational flowmeter from which the measurement time interval for the flowmeter is determined.
