Abstract: A system monitors the composition of emulsions (e.g., oil/water mixtures) by measuring one or more electrical properties (e.g., dielectric constant) of the emulsion. A computer processor determines a plurality of possible solutions using a predetermined relationship between the measured electrical properties and the component fractions of the emulsion. One possible solution is determined for each component that might be the continuous phase in the emulsion. The computer processor then evaluates the component fractions resulting from each possible solution to choose which single solution is most reasonable based on known physical limits for a continuous phase emulsion involving the component associated with each possible solution. The component fractions associated with the selected solution are output by the processor.
