Coriolis Flow Meter

摘要

A Coriolis flow meter for measuring a liquid volume fraction of a multiphase flow. The Coriolis meter includes a vibrating measurement conduit through which the multiphase flow, a wet gas flow or the like, is flowed and measured and/or analyzed. Operation of the Coriolis flow meter includes obtaining a measure of the input energy required to vibrate the conduit and a measure of the vibrational energy of the conduit, and determining the liquid volume fraction of the wet gas flow from the input energy and the vibrational energy. The liquid volume fraction may be used to correct other measurements made by the Coriolis flow meter such as density or mass flow rate.
