Abstract: The means and method of the present invention includes a source of microwave energy and associated elements which provide microwave energy to a petroleum stream. Other circuitry include elements which receive microwave energy from the petroleum stream. Electronic apparatus provides at least one outputs utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent gas and 100 percent water, corresponding to a ratio of gas to liquid. From the readings of attenuation and phase shift, an estimate of the proportions in the mix is extracted by interpolation.

Abstract: The means and method of the present invention includes a source of microwave energy and associated elements which provide microwave energy to a petroleum stream. Other circuitry include elements which receive microwave energy from the petroleum stream. Electronic apparatus provides at least two outputs utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent solids of one specie and 100 percent water, corresponding to different ratios of ratios involving oil and water, oil and solids, and water and solids.

Abstract: 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.
