Meter proving method and system

1. A method 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 a batch 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;

wherein generating the meter volume based on the flow rate does not involve generating a pulse train output signal by the flow meter; and

wherein generating the meter volume based on the flow rate does not involve generating the meter volume based on an attribute of the pulse train.

2. The method as defined in claim 1 further comprising:

wherein measuring further comprises accumulating batch flow rate values during the prover time; and

wherein generating the meter volume further comprises calculating an average flow rate over the prover time using the batch flow rate values and multiplying the average flow rate by an amount of time represented by the prover time.

3. The method as defined in claim 1 further comprising:

wherein measuring further comprises calculating a first batch flow rate by the flow meter, the first batch flow rate based on a plurality of individual flow rate values during a first batch time period that corresponds only in part to the prover time;

identifying an overlapping period corresponding to the overlap in time between the prover time and first batch time period; and

excluding from generating the meter volume individual flow rate values outside the overlapping period.

4. The method as defined in claim 3 wherein calculating further comprises calculating an average flow rate over the overlapping period.

5. The method as defined in claim 1 further comprising:

wherein measuring further comprises calculating a first batch flow rate by the flow meter, the first batch flow rate based on a plurality of individual flow rate values during first batch time period that corresponds only in part to the prover time;

wherein generating meter volume over the prover time further comprises generating based on the first batch flow rate.

6. The method as defined in claim 5 further comprising:

identifying an overlapping period of time as between the prover time and the first batch time period;

interpolating to determine a first interpolated flow rate, the interpolating based on the first batch flow rate and the overlapping period of time; and

wherein generating meter volume further comprises generating based on the first interpolated flow rate.

7. The method as defined in claim 5 further comprising:

identifying an overlapping period of time as between the prover time and first batch time period;

obtaining an equation for a line that runs substantially through a value of the first batch flow rate and values for subsequent batch flow rates, which batch flow rates correspond in whole or in part to the prover time;

using the equation to determine a solved flow rate during the overlapping period of time; and

wherein generating meter volume further comprises generating based on the solved flow rate.

8. The method as defined in claim 1 wherein establishing further comprises establishing using the prover having a prover element that travels in the fluid.
