Abstract: A vibratory flowmeter (5) for meter verification is provided, including meter electronics (20) coupled to the first and second pickoff sensors (170L, 170R) and coupled to a driver (180), with the meter electronics (20) configured to: vibrate the flowmeter assembly (10) in a single mode using the driver (180), determine a single mode current (230) of the driver (180) and determine first and second response voltages (231) generated by the first and second pickoff sensors (170L, 170R), respectively, compute frequency response functions for the determined first and second response voltages (231) from the determined single mode current (230), fit the generated frequency response functions to a pole-residue model, and verify proper operation of the vibratory flowmeter (5) using the meter stiffness value (216), residual flexibility (218), and the meter mass (240) in embodiments.
