Abstract: Methods for operating a flowmeter diagnostic tool are provided that comprise interfacing the diagnostic tool with a flowmeter (5) sensor assembly (10). A base prover volume (BPV), a desired number of passes per run, and/or a maximum number of allowed runs may be input into the diagnostic tool. Flowmeter data is received. An estimated total prove time (TPT) necessary to pass a predetermined repeatability requirement, an estimated minimum number of runs needed to achieve the calculated TPT, and/or an estimated minimum BPV may be calculated.

Abstract: A meter electronics (20) for determining a decay characteristic of a meter assembly (10) of a flow meter (5) is provided. The meter electronics (20) includes an interface (201) for receiving a vibrational response from a meter assembly (10), the vibrational response comprising a response to an excitation of the meter assembly (10) at a substantially resonant frequency, and a processing system (203) in communication with the interface (201). The processing system (203) is configured to receive the vibrational response from the interface (201), determine a response voltage (V) of the vibrational response, determine a decay characteristic (ζ) of the meter assembly (10) based on the response voltage (V), and compensate the decay characteristic (ζ) by using a previously determined decay characteristic-to-response voltage relationship.

Abstract: A method for calibrating a flowmeter is provided that comprises determining a relationship between tube period ratio and a flow tube temperature compensation (FTC) value for a plurality of flowmeters. Tube periods of the flowmeter under test are measured. A stiffness-correlated FTC is calculated using the determined relationship between the tube period ratio and the FTC value for the plurality of flowmeters and the measured tube periods of the flowmeter under test. The stiffness-correlated FTC is applied to an operating routine (314) of the flowmeter under test.
