摘要： A vibratory meter (5, 1600) configured to predict and reduce noise in the vibratory meter (5, 1600). The vibratory meter (5, 1600) includes a sensor assembly (10, 1610) and a meter electronics (20, 1620) in communication with the sensor assembly (10, 1610). The meter electronics (20, 1620) is configured to provide a drive signal to a sensor assembly (10, 1610), receive a sensor signal from the sensor assembly (10, 1610) having one or more components, and generate a signal to be applied to one of the sensor signal and the drive signal to compensate for the one or more components.

摘要： A method and apparatus for a flowmeter (5) is provided. The method comprises the steps of placing a material in a flow tube (130, 130′) while exciting a vibration mode of the flow tube (130, 130′). Exciting the vibration mode of the flow tube (130, 130′) comprises the steps of periodically driving a first driver (180L) with a first signal and periodically driving a second driver (180R) with a second signal, wherein the second driver (180R) is driven essentially in phase with the first driver (180L), but wherein the first driver's (180L) drive amplitude modulated signal reaches a maximum amplitude when the second driver's (180R) drive modulated signal reaches a minimal amplitude, and the first driver's (180L) drive amplitude modulated signal reaches a minimum amplitude when the second driver's (180R) drive amplitude modulated signal reaches a maximum amplitude. The method also comprises the steps of measuring the relative phase between a first pickoff (170L) and a second pickoff (170R) and determining a relative phase of a right eigenvector for the flow tube (130, 130′).

摘要： A meter verification method for a vibratory flowmeter (5) is provided, comprising vibrating a sensor assembly (10) of the vibratory flowmeter (5) with a plurality of test tones in a vibration mode using a driver (180), wherein the plurality of test tones is applied substantially instantly, in the absence of a ramp function. A driver (180) current is determined, and response voltage of pickoff sensors (170L, 170R) are determined for the vibration mode. The instantaneous frequency of the pickoff sensor (170L, 170R) signals is measured, and a filter is applied to isolate the response at each of the plurality of test tones. The filter is also applied to the instantaneous frequency measurements. The same delay is applied to the frequency measurements and the response at each of the test tones. A meter stiffness value (216) is generated using the current (230) and the response voltage (231), and proper operation of the vibratory flowmeter (5) is verified using the meter stiffness value (216).
