<p>A process and an instrument for determining the proportions of gas, water and oil in a gas/water/oil mixture. In the process the permittivity and the dielectric loss in the three-component mixture is being measured during passing said mixture in a flow through a spacing between two opposite electrodes. Signals received from said electrodes are processed in a computer by incorporating specific equations therein and progressively determining said proportions. The instrument comprises an electrode impedance sensor located in a concentrated flow of said three-component mixture, an impedance sensor head, a screen, impedance electronics comprising a tuned amplifier and a phase locked loop circuit forming a tracking resonance system, and a computer for processing the electronic signals and determining said proportions.</p> |
