Abstract: A meter electronics (20) and a method for detecting and identifying a change in a vibratory meter (5) is provided. The meter electronics (20) includes an interface (201) configured to receive sensor signals (100) from a meter assembly (10) and provide information based on the sensor signals (100) and a processing system (202) communicatively coupled to the interface (201). The processing system (202) is configured to use the information to determine a first stiffness change (244) associated with a first location of a conduit (130, 130′) of the vibratory meter (5), determine a second stiffness change (254) associated with a second location of the conduit (130, 130′) of the vibratory meter (5), and determine a condition of the conduit (130, 130′) based on the first stiffness change and the second stiffness change.

Abstract: Vibratory meters (5), and methods for their use measuring a fluid are provided. Each vibratory meter includes a multichannel flow tube (300) comprising two or more fluid channels (302), a pickoff (170), a driver (180), and meter electronics (20) configured to apply a drive signal to the driver at a drive frequency ω, and measure a deflection of the multichannel flow tube with the pickoff. In examples, at least one fluid channel has an effective diameter that is related to velocity of sound and drive velocity. In further examples, the driver may apply a drive signal to the driver having a drive frequency proportional to the velocity of sound and effective diameter.

Abstract: A method for determining a lateral mode stiffness of one or more fluid tubes (103A, 103B) in a vibrating meter (5) is provided. The method comprises a step of vibrating at least one of the one or more fluid tubes (103A, 103B) in a drive mode vibration. Drive mode sensor signals (310) are received based on a vibrational response to the drive mode vibration. At least one of the one or more fluid tubes (103A, 103B) is vibrated in a lateral mode vibration, wherein the lateral mode is approximately perpendicular to the drive mode. Lateral mode sensor signals (317) are received based on a vibrational response to the lateral mode vibrations. The method further comprises determining a lateral mode stiffness (318) based on the lateral mode sensor signals (317).
