Method of determining total prove time

A method for operating a flowmeter diagnostic tool comprising:

• interfacing the diagnostic tool with a flowmeter sensor assembly;
• inputting a maximum number of allowed runs into the diagnostic tool;
• inputting a desired number of passes per run into the diagnostic tool;
• receiving flowmeter data;
• calculating an estimated total prove time (TPT) necessary to pass a predetermined repeatability requirement;
• calculating an estimated minimum base prover volume (BPV);
• calculating a standard deviation of the flowmeter sensor assembly flow rate (σ);
• determining the number of samples used to calculate σ;
• calculating a meter-specific factor (MSF).

A diagnostic tool for configuring a flowmeter system comprising:

• electronics configured to interface with a flowmeter (5) and receive flowmeter data;
• a user interface with the electronics configured to accept a user input, wherein the input comprises at least one of a base prover volume (BPV), a desired number of passes per run, and maximum number of allowed runs;
• and
• a processing system (303) configured to run a proving routine (315), wherein the proving routine (315) is configured to at least one of calculate an estimated total prove time (TPT) necessary to pass a predetermined repeatability requirement, calculate an estimated minimum number of runs needed to achieve the calculated TPT, and calculate an estimated minimum base prover volume (BPV),
• calculating a standard deviation of the flowmeter sensor assembly flow rate (σ);
• determining the number of samples used to calculate σ;
• calculating a meter-specific factor (MSF).
