METHOD FOR MEASURING WATER-OIL MIXTURES WITH RELATIVELY HIGH GAS CONTENT

摘要

The concentration of one liquid, such as water, in another liquid, such as crude or refined oil, existing in a mixture which also includes entrained gas is carried out by an apparatus (Fig. 1, 10) whic h measures a change in a microwave oscillator (30} op- erating frequency and the difference between incident and transmitted power with respect to a measurement section of the appar- atus (10). Continuous monitoring (60) of the difference in incident versus transmitted power is carried out to detect the presence of gas and then selectively averaged peak values of the concentration of one liquid in another are determined to provide an accu- rate measurement (62) of the content of water in oil even with the presence of various amounts of entrained gas in the mixture.
