CPC G01F 1/8436 (2013.01) [G01F 1/8431 (2013.01); G01F 1/8477 (2013.01)] | 16 Claims |
1. A meter electronics (20) for determining a damping of a meter assembly (10) of a flow meter (5), the meter electronics (20) comprising 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) comprising a storage system (204) including a routine and a process device in communication with the interface (201), the storage system (204) and the routine being configured to cause the meter electronics (20) to:
receive the vibrational response from the interface (201);
measure a plurality of response voltages (V) of the vibrational response, the plurality of response voltages (V) including one or more decay sections (430a, 530a-530f) and one or more rising sections (430b, 630a-630f); and
determine an aggregate damping-related value of the meter assembly (10) based on a decay characteristic (ζ) value determined from the one or more decay sections (430a, 530a-530f) and a damping characteristic (C) value determined from the one or more rising sections (430b, 630a-630f).
