ABSTRACT:
A dual frequency microwave water cut monitor includes a microwave source which provides microwave energies at two different frequencies to a circulator which in turn provides the microwave energies to an antenna. The antenna provides the microwave energies to a petroleum stream and also receives reflected microwave energy back from the stream. The reflected microwave energy is provided by the antenna to the circulator which in turn provides the reflected microwave energies as test microwave energies. A detector assembly connected to the circulator detects the intensities of the test microwave energies and provides a corresponding intensity signal. Indicator apparatus connected to the circulator to the microwave source and to the detector assembly provides an indication of the water cut of the petroleum stream in accordance with the intensity signal and the phase difference between one of the source provided microwave energies and its corresponding test microwave energy.
