Zusammenfassung:A meter electronics (20) for determining a damping of a meter assembly (10) of a flow meter (5) is provided. The meter electronics (20) includes an interface (201) for receiving a vibrational response from a meter assembly (10), the vibrational response comprising a response to an excitation of the meter assembly (10) at a substantially resonant frequency, and a processing system (203) in communication with the interface (201). The processing system (203) is configured to receive the vibrational response from the interface (201) and measure a plurality of response voltages (V) of the vibrational response, the plurality of response voltages (V) including at least one of one or more decay sections (430a, 530a-530f) and one or more rising sections (430b, 630a-630f). The processing system (203) is also configured to determine an aggregate damping-related value of the meter assembly (10) based on at least one of the one or more decay sections (430a, 530a-530f) and the one or more rising sections (430b, 630a-630f).
