Claim:
1. A method for determining a lateral mode stiffness of one or more fluid tubes in a vibrating meter, comprising steps of: vibrating at least one of the one or more fluid tubes in a drive mode vibration, with a first driver; receiving drive mode sensor signals based on a vibrational response to the drive mode vibration with a first pickoff; vibrating at least one of the one or more fluid tubes in a lateral mode vibration, wherein the lateral mode is substantially perpendicular to the drive mode with a second driver; receiving lateral mode sensor signals based on a vibrational response to the lateral mode vibrations with a second pickoff; and determining a lateral mode stiffness based on the lateral mode sensor signals; wherein the first driver is oriented substantially perpendicularly to the second driver, and the first pickoff is oriented substantially perpendicularly to the second pickoff.
