Abstract
A system of transducers and electrical circuitry connecting with the transducers detects and locates flaws in the metallic walls of vessels used for containing and transporting liquids. An array of transducers is carried by a sled having rollers for facile movement about the surface of the vessel which surface is submerged within the liquid to permit the liquid to provide a sound propagating medium between the transducers and the vessel wall. The transducers are arranged in sets of two transducers, one of which is a transmitting transducer and the other a receiving transducer, the two transducers being positioned in tandem for increased azimuthal coverage of the sonic radiation.
