Abstract

Techniques are described for accurately measuring a density or other parameter of a fluid traveling through a vibratable conduit (215), using a flowmeter (200). 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 (1406). Using the measurements, a corrected frequency corresponding to a zero phase difference can be estimated (1408), and this corrected frequency can be used to perform density calculations (1506). These techniques remove an undesirable dependency between the frequency/phase difference variables.
