Claim 13:
14. A method comprising:
coupling a pig to a cylindrical elongated body of a pipeline profiler;
inserting the pig and the pipeline profiler into a pipeline;
engaging an inner wall of the pipeline by a plurality of odometers coupled to the cylindrical elongated body by a plurality of mechanical arms attached radially about the cylindrical elongated body and having adjustable angle bracket shapes, the mechanical arms carrying elements that bias the odometers away from the cylindrical elongated body;
wherein each mechanical arm comprises a first linearly adjustable arm and a second linearly adjustable arm arranged to form the adjustable angle bracket shape,
wherein a first end of the first linearly adjustable arm and a first end of the second linearly adjustable arm of each mechanical arm:
are coupled together by the respective hinge joint of the mechanical arm, and
pivot relative to each other at the respective hinge joint of the mechanical arm, and

wherein a second end of the first linearly adjustable arm and a second end of the second linearly adjustable arm of each mechanical arm are pivotally coupled to the cylindrical elongated body at axially spaced apart locations along the cylindrical elongated body, whereby an axial midpoint of the cylindrical elongated body is located axially between the spaced apart locations,
propelling the pig and pipeline profiler along the pipeline by a fluid pressure in the pipeline;
during the propelling, measuring a distance traveled by the pipeline profiler by the plurality of odometers;
during the propelling, detecting an acceleration of the pipeline profiler by a first motion device mounted on the cylindrical elongated body; and
during the propelling, detecting an orientation of the pipeline profiler by a second motion device mounted on the cylindrical elongated body.
