Abstract
A meter electronics () for generating a drive signal for a vibratory flowmeter () is provided according to an embodiment of the invention. The meter electronics includes an interface () and a processing system (). The processing system is configured to receive the sensor signal () through the interface, phase-shift the sensor signal () 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 () and the phase-shifted sensor signal in order to generate a drive signal phase (). The processing system is further configured to determine a sensor signal amplitude () from the sensor signal () and the phase-shifted sensor signal, and generate a drive signal amplitude () based on the sensor signal amplitude (), wherein the drive signal phase () is substantially identical to a sensor signal phase ().
