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

Vibratory flowmeter and methods and diagnostics for meter verification

A dongle () for controlling access to an interface () is provided. The dongle () includes a dongle memory () configured to communicatively couple to the interface (), the dongle memory () comprising a program code () that includes authorized menus (), wherein the program code () is configured to authorize access to one or more menus on the interface ().

Controlling access to an interface with a dongle

A field service device () for facilitating a processing system replacement in a vibratory flowmeter is provided. The field service device () includes a field service device processor () configured to interface with one or more vibratory flowmeter processing systems and a storage system () configured to store pre-replacement operationally-derived values (), post-replacement operationally-derived values (), and one or more scaling factors (). The field service device processor () is configured to obtain pre-replacement operationally-derived values (), obtain post-replacement operationally-derived values () after an old processing system has been replaced with a replacement processing system, generate the one or more scaling factors () as a ratio of one or more pre-replacement operationally-derived values () to one or more post-replacement operationally-derived values (), and download the one or more scaling factors ().
