Title: Apparatus and method for void/particulate detection

Abstract

Apparatus and method for detecting voids and particulates in a fluid within a containing vessel. A diffuse ultrasonic signal is coupled into the fluid by a first transducer and the portion of the ultrasonic signal transmitted through the fluid is detected by a second transducer. The received signal is analyzed by a processor to determine the void fraction of the fluid responsive to the attenuation of the received ultrasonic signal. In addition, voids and particulates are detected by evaluating the increase in side-band energy of the received signal.
