US patent no. 7,065,455 B2: Correcting frequency in flowtube measurements
Techniques are described for accurately measuring a density or other parameter of a fluid traveling through a vibratable conduit, using a flowmeter. The techniques involve obtaining measurements of a frequency of vibration of the conduit, as a function of a phase difference between two sensors measu...

| description | Techniques are described for accurately measuring a density or other parameter of a fluid traveling through a vibratable conduit, using a flowmeter. The techniques involve obtaining measurements of a frequency of vibration of the conduit, as a function of a phase difference between two sensors measuring the vibration. Using the measurements, a corrected frequency corresponding to a zero phase difference can be estimated, and this corrected frequency can be used to perform density calculations. These techniques remove an undesirable dependency between the frequency/phase difference variables. |
