Claim 0:
1. A method of operating a 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 method comprising:
measuring, at two or more instances of time, at least two parameters consisting 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;
determining a density decoupling parameter at a plurality of different gas void fractions for which the density decoupling parameter determined for the at least two of the instances of time differ; and
determining a model for the density decoupling parameter as a function of gas void fraction.
