An apparatus is described for detecting voids and particulates in a fluid within a containing means. The apparatus comprises: (a) first transducer means, coupled to a first location on the containing means, for transmitting a diffuse sound field of predetermined frequency into the fluid; (b) second transducer means, coupled to a second location on the containing means, for receiving a portion of the transmitted sound field and for generating a signal representative of the received portion of the sound field; and (c) signal processing means, coupled to the second transducer, for processing the second transducer signal to determine the presence of voids and particulates responsive to attenuation of the sound field transmitted through fluid.
