Classification: CPC G | IPC G

Claim 9:
10. An improved Coriolis meter having a process fluid comprising a bubbly mixture flowing therein, the process fluid having a density of a liquid phase and a gas void fraction, the improved Coriolis meter comprising:
the improved Coriolis meter configured to measure, at two or more instances of time, at least two of:
a first natural frequency of a process conveying flow tube;
a second natural frequency of the process conveying flow tube; and
a sound speed of the process fluid;

wherein, at the two or more instances of time, the density of the liquid phase of the bubbly mixture is substantially constant and the gas void fraction of the process fluid is substantially different;
a processor configured to determine a density decoupling parameter at a plurality of different gas void fractions, wherein the density decoupling parameter differs as function of gas void fraction; and
a model configured to determine the density decoupling parameter as a function of gas void fraction.
