Patent ID: 8887579

Claim:
A digital flowmeter comprising: a vibratable conduit; a driver connected to the conduit and operable to impart motion to the conduit; a first sensor connected to the conduit and operable to sense the motion of the conduit and generate a first sensor signal representative of said sensed motion, wherein said first sensor signal is a periodic signal having a first amplitude and a first frequency; a second sensor connected to the conduit and operable to sense the motion of the conduit and generate a second sensor signal representative of said sensed motion, wherein said second sensor signal is a periodic signal having a second amplitude and a second frequency; and a control and measurement system connected to the driver, the first sensor, and the second sensor, the control and measurement system comprising circuitry to: receive a first sensor signal from the first sensor, receive a second sensor signal from the second sensor; compute a corrected first amplitude as a function of the first amplitude of the received first sensor signal; compute a corrected second amplitude as a function of the second amplitude of the received second sensor signal; and generate a measurement of a property of material flowing through the conduit as a function of the corrected first amplitude and the corrected second amplitude.
