Abstract
The invention relates to an ultrasonic measuring apparatus for determining the geometrical position of a boundary between two materials in a first material from a reference place, more particularly for wall thickness or fault testing. To enable even very thin-walled materials to be measured, the measuring apparatus isolates the reflected ultrasonic signals from the ultrasonic mixed signal received by the receiver, which consists of the ultrasonic signal reflected at the boundary to the first material and the ultrasonic signal reflected at the boundary to the second material, so that the time of impingement of the reflected signal is clearly determined for the determination of propagation time.
