  • Patent number: 10605647
    Abstract: 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.

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).

  • Publication number: 20190310121
    Abstract: A method of determining optimal resistance and compensating for temperature variations in determining a test tone is presented. The optimal resistance in a drive circuit amplifier and drive coil and using the optimal resistance to improve the accuracy of a test tone used in the calibration of a flow meter is presented. The optimal resistance is calculated using a linear extrapolation of the resistance change of the circuit with respect to temperature. The optimal resistance is then used to calculate the proper maximum sensor current (MSC) value using an equation derived from Ohm's law, and from the MSC a test tone level is calculated.
