<p num="1"><br/><br/><br/>Meter electronics (20) for a flow meter (5) is provided according to an <br/>embodiment of the invention. The meter electronics (20) includes an interface <br/>(201) for receiving a vibrational response from the flow meter (5) and a <br/>processing system (203) in communication with the interface (201). The <br/>vibrational response is a response to a vibration of the flow meter (5) at a <br/>substantially resonant frequency. The processing system (203) is configured to <br/>receive the vibrational response from the interface (201), determine a <br/>frequency (.omega.0) of the vibrational response, determine a response voltage <br/>(V) and a drive current (I) of the vibrational response, measure a decay <br/>characteristic (.zeta.) of the flow meter (5), and determine the stiffness <br/>parameter (K) from the frequency (.omega.0), the response voltage (V), the <br/>drive current (I), and the decay characteristic (.zeta.).<br/>
