<p num="1"><br/><br/><br/>A meter electronics (20) for generating a drive signal for a vibratory <br/>flowmeter (5) is provided according to an embodiment of the invention. The <br/>meter electronics includes an interface (201) and a processing system (203). <br/>The processing system is configured to receive the sensor signal (201) through <br/>the interface, phase-shift the sensor signal (210) substantially 90 degrees to <br/>create a phase-shifted sensor signal, determine a phase shift value from a <br/>frequency response of the vibratory flowmeter, and combine the phase shift <br/>value with the sensor signal (201) and the phase-shifted sensor signal in <br/>order to generate a drive signal phase (213). The processing system is further <br/>configured to determine a sensor signal amplitude (214) from the sensor signal <br/>(210) and the phase-shifted sensor signal, and generate a drive signal <br/>amplitude (215) based on the sensor signal amplitude (214), wherein the drive <br/>signal phase (213) is substantially identical to a sensor signal phase (212).<br/>
