... electromagnetic wave transmits in the coaxial sensor full of mixed fluid of water and oil, the wave phase shifts regularly. The water cut of the mixed fluid is calculated through the measured phase variation. Based on the analysis of polarization principle, dielectric property, transmission law, and the circuit...
