Apparatus for the measurement of the fraction of gas in a two- component fluid flow comprising a liquid and a gas in mixture

摘要

The apparatus has two plate electrodes surrounded by a third electrode. The third electrode is maintained at an electric potential equal to half of the electric potential between the two plate electrodes. The fluid is passed between the two plate electrodes and the changes in capacitance between the two plate electrodes is measured. From this measurement the fraction of gas in the fluid is determined.
