Abstract: A meter proving method and system. At lease some of the illustrative embodiments are methods comprising establishing a prover time by a prover device, measuring a flow rate of a fluid with a flow meter that uses multiple measurements taken over a period of time to produce each individual flow rate value (the flow meter electrically coupled to the prover device), and generating a meter volume over the prover time based on the flow rate. The generating the meter volume based on the flow rate does not involve: generating a pulse train output signal by the flow meter; and generating the meter volume based on an attribute of the pulse train.

Abstract: A system and method is configured to take a “snapshot” of data received by a meter or measurement device so that it may be later frozen or duplicated in a manner identical to that of the meter. The system includes recording a continuous stream of raw data into a format suitable for transport to a site better suited for debug and diagnosis, and replaying the data on a replay device such that time, as seen by the system, may be “frozen” at will and any instant of the stream examined.

Abstract: A method and related ultrasonic meter identify and correct for transit time errors such as peak switch errors. The method includes calculating values for a set of diagnostics from measurements of the fluid flow, including transit time measurements. Based on the values for the diagnostics, and whether and how they fall outside of their respective ranges, the meter can identify a variety of problems with the meter or fluid flow, such as whether there has been an intermittent peak switch, a permanent peak switch, or the presence of noise, velocity pulsation in the fluid flow, temperature stratification, or other problem. In the event there is a problem with the meter, the meter self-tunes in order to minimize the chances of the problem happening again.
