Abstract
In this embodiment the size distribution of particles in a fluid is determined by performing the following steps: (a) passing a plurality of ultrasonic beams through the fluid, wherein the beams have respective frequencies; (b) obtaining a velocity measure of the beams in the fluid; (c) obtaining an ultrasonic velocity spectrum as a function of particle size for the fluid; (d) determining from the attenuation of gamma-rays the density of the fluid; and (3) calculating the particle size distribution for the fluid from the velocity measure, the velocity spectrum, and the suspension density which were respectively obtained in steps (b), (c) and (d).
