Radiation Attenuation Method of Measuring Density of a Two-Phase Fluid

Abstract

A gamma‐ray attenuation technique is presented for measuring density and phase distribution in a two‐phase fluid. A comparison is made between a ``one‐shot'' and traverse method. The technique was evaluated on Lucite mock‐ups of simulated flow patterns encountered in two‐phase flow and by a series of tests on an air‐water system at atmospheric pressure.
