Abstract
A system for continuously determining the eccentric characteristics of a tube wall, including a positioning assembly supported by the tube when it travels in its lengthwise direction. Two thickness sensors are supported by the positioning assembly and have sensing axes disposed in a predetermined angular relation with respect to one another about the periphery of the tube. The two sensors continuously measure the wall thickness of the tube at the predetermined angular locations as the tube moves in its lengthwise direction. Signal processing circuits are provided for continuously computing the eccentricity characteristics of the tube based entirely upon the comparative values of the thickness readings of the sensors.
