Patent ID: 7690240

Claim:
A method of calibrating a flowmeter having a vibratable flowtube and at least one sensor associated with the vibratable flowtube, the method comprising: vibrating the flowtube while a first operational parameter of the flowtube is present; receiving a first sensor signal from the sensor, the sensor signal representative of the vibration of the flowtube while the first operational parameter of the flowtube is present; determining a first calibration value based on the first sensor signal, wherein the first calibration value is a first zero-flow calibration value; storing the first calibration value in association with the first operational parameter; vibrating the flowtube while a second operational parameter of the flowtube is present; receiving a second sensor signal from the sensor, the second sensor signal representative of the vibration of the flowtube while the second operational parameter of the flowtube is present; determining a second calibration value based on the second sensor signal, wherein the second calibration value is a second zero-flow calibration value; and storing the second calibration value in association with the second operational parameter.
