Abstract
A vibratory meter () is provided, including one or more flow conduits (), one or more pickoff sensors ('), and a driver (). Meter electronics () is configured to vibrate the one or more flow conduits () using a drive signal including an initial vibration frequency and to receive a pickoff sensor signal from the one or more pickoff sensors (′) in response, iteratively offset a phase difference between the drive signal and the pickoff sensor signal by a predetermined phase increment and measure a resulting vibrational frequency and amplitude, with the offsetting operatively sweeping the vibration frequency over a predetermined vibration frequency range and therefore generating a plurality of vibration amplitudes and a corresponding plurality of vibration frequencies, and determine a substantially maximum amplitude response in the plurality of vibration amplitudes and designate the corresponding vibration frequency as comprising the resonant frequency.
