| 摘要 |
<p>The invention relates to an apparatus for characterizing an effluent formed by a multiphase fluid mixture, said apparatus comprising a source emitting gamma rays at a plurality of energy levels through said effluent towards a detector block that takes account of the photons it receives as a consequence thereof to deduce therefrom the attenuation of said rays by said effluent. According to the invention, the detector block includes a filter for selectively detecting the photons it receives at a first energy level and at a second energy level, said first and second levels being predetermined amongst the energy levels of radiation from the source.</p> |
