Abstract:
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 (ω0) of the vibrational response, determine a response voltage (V) and a drive current (I) of the vibrational response, measure a decay characteristic (ζ) of the flow meter (5), and determine the stiffness parameter (K) from the frequency (ω0), the response voltage (V), the drive current (I), and the decay characteristic (ζ).
