Meter electronics (20) for a flow meter (5) is provided according to an embodiment of the invention. The meter electronics (20) includes an interface (201) for receiving a vibrational response from the flow meter (5) and a processing system (203) in communication with the interface (201). The vibrational response is a response to a vibration of the flow meter (5) at a substantially resonant frequency. The processing system (203) is configured to receive the vibrational response from the interface (201) determine a , frequency (.omega.0) of the vibrational response determine a response voltage , (V) and a drive current (I) of the vibrational response measure a decay , characteristic …
