Title: Inside diameter, outside diameter and wall tube gage

Abstract: An ultrasonic apparatus and technique for rapidly and accurately measuring the inside and outside diameters and wall thickness of a tubular material. The tubes are passed between a pair of diametrically opposed ultrasonic transducers for obtaining the necessary data. A third transducer is employed to obtain a reference signal, which is used to automatically compensate for any temperature variations in the ultrasound couplant medium.
