Abstract
A method for verifying accurate operation for a flow meter () is provided. The method entails receiving a vibrational response from the flow meter (), wherein the vibrational response comprises a response to a vibration of the flow meter () at a substantially resonant frequency. At least one gain decay variable is measured. It is then determined whether the gain decay variable is outside a predetermined range. A filter used in a stiffness calculation is adjusted if the gain decay variable is outside the predetermined range. The ability to detect and/or quantify any changes to the stiffness of the meter assembly in order to maintain a high level of accuracy is an improvement in the field of flow meters.
