The invention relates to a method and an apparatus for determining the cut (percentage) of one component of a multiphase fluid flowing in a pipeline, for example, oil or other hydrocarbon in a fluid flow that comprises oil, water, gas, and soil components, by use of NMR analysis. The fluid is flowed ...

Apparatus for detecting the magnitude of a property of a fluid including a body mounted on a torsion spring that is oscillated by a feedback of alternately an in-phase and an out-of-phase signal from an amplifier having a gain adequate to sustain the oscillations. If the in-phase signal has a freque ...

Gerald L Schlatter, Robert L Poland: Extreme temperature flow meter. Engineering Measurements Company, James R Young, March 6, 1990: US04905522 (2 worldwide citation)

A flowmeter has an elongated probe with a rotor positioned at the distal end of the probe for insertion into a fluid flow and an elongated conductor in the probe that terminates adjacent the rotor. A signal generator induces a standing wave on the conductor, and rotation of the rotor, which acts as ...
