Multifrequency acoustic measurement of concentration .The paper describes an ultrasonic backscatter device for measuring vertical profiles of the concentration of suspended sand in water in the presence of air bubbles. The use of six frequencies permits a simultaneous measurement of the concentration of suspended sand, the grain size, and the concentration of air bubbles.
