Abstract
A method for measuring and aligning a rotary cylindrical or other rotationally symmetrical apparatus, such as a kiln or a drum. The apparatus to be measured and aligned has a shell and at least one supporting ring. As the rotary apparatus is rotating under process conditions, measurement points are measured on the surface of the rotating object's shell in the axial direction on both sides of each supporting ring on the same circumferential line. Regression circles are calculated from the measured points, center points are determined for the calculated circles and a straight line and its center point are determined between the center points of the circles calculated on both sides of each supporting ring. A reference straight line is calculated for the center line of the shell and the object's shell is aligned to be straight by transferring the determined center points of the shell to the calculated reference line.
