Abstract
A clamp on ultrasonic transducer having a clamping element which can be positioned around a conduit with the inner portion of the clamping element being formed to fit closely against the outer wall of the conduit, thus defining at a selected position along the conduit a transverse reference plane. The clamping element carries on it one or more channels extending parallel to the axis of the conduit with ultrasonic transducing elements adjustably mounted on those channels such that their contact pressure with the conduit can be independently adjusted. The ultrasonic transducing elements then form a path of ultrasonic interrogation in a plane parallel to the axis of the conduit and at a position defined by the transverse reference plane.
