Claim 0:
1. A geometry sensor for pipeline inline inspection tool, said geometry sensor comprising:
an arm pivotally mounted to a body of the inline inspection tool;
a magnet mounted to the arm, the magnet having an annular shape with a hole having an axis centered in the hole and a magnetic field having a north pole and a south pole located on opposing sides of the hole on an axis that runs perpendicular to the axis centered in the hole;
an axis of rotation of the arm aligned with the axis centered in the hole; and
a Hall effect sensor fixed relative to the body of the of the inline inspection;
wherein an outer end of the arm moves along an interior surface of a conduit as the tool passes through the conduit with the arm and magnet pivoting relative to the body and the Hall effect sensor can detect movement in the magnetic field and the axis of rotation of the arm is perpendicular to the axis between the north and south poles.
