摘要： The conductance meter includes source means which irradiates a fluid with microwave energy. A receiver receives microwave energy that has passed through the fluid and provides the received microwave energy as test microwave energy. Electronic apparatus determines the conductance of the fluid in accordance with the amplitude of the test microwave energy and the phase difference between the microwave energy from the source and the test microwave energy from the receiver where only 1 microwave frequency is used.

摘要： A co-variance microwave water cut monitor includes a test cell having a petroleum stress flowing through it while permitting the microwave energy to enter the test cell. A microwave source provides microwave energy to a circulator which in turn provides the microwave energy to an antenna. The antenna provides the petroleum stream in the test cell with the microwave energy and 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 energy as test microwave energy. A detector assembly connected to the circulator detects the intensity of the test microwave energy 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 the source provided microwave energy and the test microwave energy.

摘要： A petroleum stream microwave water cut monitor includes test cell means which contains a reference petroleum multiphase fluid sample and which has a sample stream of a petroleum stream passing through it. A source transmits microwave energy to one of a first pair of antennae which irradiates the petroleum stream flowing in the test cell or the reference sample in the test cell with microwave energy. One of a second pair of antennae receives the microwave energy that has passed through either the petroleum stream or the reference sample. A detector detects the received microwave energy and provides a signal corresponding thereto. An indicator provides an indication of the water cut of the petroleum stream in accordance with the received signal power and a phase difference between the transmitted microwave energy and the received microwave energy.

摘要： The watercut of fluid in a mulitphase flow is measured. Microwave energy in the 10 Ghz range is transmitted through a test call having flow passing therein through a known geometry. Attenuation and phase shift of the microwave energy is measured and used to derive the wave number of the microwaves in the unknown fluid. The water fraction of the unknown fluid is then determined from the wave number and the known geometry of the test all using Hannai's equation.

摘要： A system determines the relative amounts of phases in multiphase flow, typically the liquid (or gas) fraction of a stream in two-phase flow. More particularly, the system quickly and reliably determines the liquid (or gas) fraction of a flowing two-phase stream, such as a process stream commonly found in chemical processing or in petroleum production operations. The system yields accurate results regardless of the exact flow regime under which the two-phase stream is flowing.
