Abstract
An ultrasonic technique was developed to measure the concentration of solids in a three-phase slurry reactor. Preliminary measurements were taken on slurries consisting of water, glass beads, and nitrogen bubbl es. The data show that the speed and attenuation of the sound are well defined functions of the solid and gas concentrations in the slurries . A simple model is proposed to correlate the concentration of solids with the measured characteristics of the ultrasonic signals.
