  • Apparatus and method for fluid phase fraction determination using X-rays
    Patent number: 9448189
    Abstract: An apparatus for determining fluid phase fraction of a multiphase fluid mixture (13) comprises: —a x-ray generator (20) arranged to emit a x-ray radiation spectrum comprising a low energy region and a high energy region, the high energy region including a Bremsstrahlung spectrum; —a pipe section (27) through which the multiphase fluid mixture (13) flows comprising a measurement section (28), said measurement section (28) being coupled to said x-ray generator (20); —a detector (30) coupled to said measurement section (28) and arranged to detect x-ray radiation that has passed through said multiphase fluid mixture (13), the detector (30) being coupled to a multichannel analyzer (32) producing a measurement output comprising a low energy (LE) and high energy (HE) measurement counts; wherein the measurement output further comprises a low energy (LV) and high energy (HV) control counts, in a low energy and high energy control windows located on an edge of the Bremsstrahlung spectrum, respectively; and wherein the

  • Method and apparatus for determining volume fractions in a multiphase flow
    Patent number: 8855263
    Abstract: A method, apparatus and computer program product for measuring a composition of a multiphase fluid, including radiating a photon beam through the multiphase fluid and measuring radiation absorption by the multiphase fluid for at least three energy levels to obtain measured radiation absorption data, and providing the measured radiation absorption data to processing unit configured to calculate the composition of the multiphase fluid using the measured radiation absorption data, whereby an effect of an injected fluid on the absorption of the photon beam is taken into account during calculation of the composition of the multiphase fluid.
