FIELD: measuring equipment.
SUBSTANCE: apparatus for calculating the speed of axial movement relative to a metal object by recording and/or building a map of non-homogeneities of a magnetic field comprises sensors for consecutively measuring the external magnetic field, while containing a platform with external magnetic field sensors fixed thereon, placed at a known distance from each other, at least two located along the axis of movement of the apparatus.
EFFECT: accuracy of measurements and versatility of the apparatus, possibility of use thereof as an odometer, e.g., for measuring the length of structures in pipelines and pipelines themselves.
