摘要： A system and method for measuring a pipe is provided. The system includes a frame rotatably receiving the pipe, a carriage movably positionable along the frame, a guide floatingly positionable about the carriage, at least one sensor for measuring a position of the pipe, and a measurement unit operatively linked to the sensor for collecting measurements therefrom. The guide has a mouth that receivingly engages the pipe and axially aligns therewith. The pipe is measured with the sensor(s) while moving at least one of the pipe, the carriage and the guide.
