A meter electronics (20) for generating a drive signal for a vibratory flowmeter (5) is provided according to an embodiment of the invention. The meter electronics includes an interface (201) and a processing system (203). The processing system is configured to receive the sensor signal (201) through the interface, phase-shift the sensor signal (210) substantially 90 degrees to create a phase-shifted sensor signal, determine a phase shift value from a frequency response of the vibratory flowmeter and combine the phase shift , value with the sensor signal (201) and the phase-shifted sensor signal in order to generate a drive signal phase (213). The processing system is further …
