Abstract
According to an illustrative embodiment, a system for calculating an average phase difference in a Coriolis flow meter includes a conduit for transferring a fluid. The conduit is caused to vibrate when the fluid flows through the conduit. The system also includes a first and a second detector operable to detect vibrations at first and second portions of the conduit, respectively. The first and second detectors measure the phase of the first and second vibrations, respectively. The system may also include a timer operable to measure a phase difference between the phases of the first and second vibrations, and a memory operable to store one or more values associated with a plurality of phase differences. The plurality of phase differences may include the phase difference measured by the timer. The system may also include a processor operable to calculate an average phase difference using the one or more values.
