Abstract
Methods and equipment suitable for measuring dimensions of a cylindrical body including systems having a housing and means for supporting the housing relative to an arcuate surface of the body. The supporting means comprises at least two wheels having axes of rotation oriented so that engaging the arcuate surface of the body with the two wheels causes edges of the two wheels to contact the arcuate surface at two terminals spaced apart by a length of a chord lying in a cross-section plane of the body. Measurement means is mounted to the housing for contacting a surface point of the body located within the length of the chord of the body, and means is provided for determining the diameter of the body based on the length of the chord determined by the two wheels and a height of the chord ascertained with an output of the measurement means.
