1. A method comprising:

  • receiving a first signal at a flowmeter, the first signal representing a motion of a flowtube;

    generating a buffered signal by storing at least one cycle of the first signal in a buffer;

    generating a second signal based on the buffered signal, the second signal being compensated for a phase delay associated with an electronic element of the, flowmeter; and

    applying the second signal to a driver coupled to the flowtube and configured to impart motion to the flowtube,wherein generating the second signal based on the buffered signal comprises selecting a value representing the phase delay from the buffer, and generating the second signal based on the value.
