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 of the three-component mixture, during passing said mixture in a flow between two opposite electrodes, is measured by a capacitive non-penetrating first sensor, whereas the density of said flowing mixture is measured by a second sensor including a radioactive element and a gamma-radiation densitometer. The electronic signals received from said sensors being processed in a computer by incorporating specific equations therein and progressively determining the proportions of said three components in said three-component mixture. The instrument comprises an electrode capacitance sensor, including two opposite electrodes located at opposite sides of an intermediate concentrated mixture flow, a capacitance sensor head, a screen, a density meter including a radioactive element and a gamma-radiation densitometer, and a computer for processing the electronic signals and determining said proportions. |
