Abstract
Device for measuring the volume of sections of a tubular blank by ultrasonic echography. An ultrasonic pulse emitter -receiver is associated with an auxiliary reflector. The transducer and the auxiliary reflector are mounted on a rotary head. The blank moves forward continuously and the ultrasonic beam describes a helix on its surface. On basis of the measurement of the distances from the transducer to the outer and inner surfaces of the tube, a computer calculates the elementary areas and volumes and compares the sum of the elementary volumes with a reference value. The sections of constant weight are marked by a component controlled by the computer.
