Abstract: Disclosed is a system and method for ultrasonic measurement of the average diameter and surface profile of a tube. A calibration block is used to calibrate the average tube diameter, and a correction is applied to account for any temperature difference of the couplant between calibration and test measurements. By using a linear probe, or a single probe with a finely pitched helicoidal scan, errors in diameter measurement due to presence of surface pits may be compensated.
