SYSTEM AND METHOD FOR MEASURING PROPERTIES OF LIQUID IN MULTIPHASE MIXTURES USING TWO OPEN ENDED COAXIAL PROBES WITH DIFFERENT SENSITIVITY DEPTHS

摘要

This disclosure describes measuring properties of a multiphase mixture flowing in a pipe using probes with different sensitivity depths. By generating annular flow of the multiphase mixture in the pipe, the probes may be contacted with the liquid phase of the mixture flowing on an inner- wall of the pipe and apparent permittivities of the annular flow measured by the probes. These measured permittivities may be processed to determine liquid fraction of the annular flow and water-in-liquid ratio of the liquid phase of the annular flow.
