Patent ID: 8000906

Claim:
A controller for a flowmeter comprising: an input module operable to receive a sensor signal from a sensor connected to a vibratable flowtube, the sensor signal related to a fluid flow through the flowtube; a signal processing system operable to receive the sensor signal, determine sensor signal characteristics, and output drive signal characteristics for a drive signal applied to the flowtube; an output module operable to output the drive signal to the flowtube; a control system operable to modify the drive signal and thereby maintain oscillation of the flowtube during a transition of the flowtube from a substantially empty state to a substantially full state; and wherein the control system is further operable to modify the drive signal and thereby maintain oscillation of the flowtube while separate batches of the fluid flow are processed through the flowtube, wherein the flowtube is substantially empty in between the separate batches.
