Abstract

A method and apparatus for characterizing a multiphase mixture by irradiating the mixture with X-rays, collecting the photons that emanate from the mixture in response to the irradiation, generating a signal responsive to the aggregate energy of the collected photons, and analyzing the signal to characterize the mixture. Preferably, the mixture is irradiated by repetitively pulsing an X-ray tube and the photons are collected using a multi-layer detector. The method and apparatus may be used to determine the flow rate, flow velocities, and/or composition of the multiphase mixture. In other embodiments, a plurality of X-ray sources and/or detectors may be used.
