Abstract

A system and method for measuring the inner space of a container provides for the measurement of the wear of the lining of a container such as a torpedo ladle optionally while the ladle is still hot. The interior lining of the container is scanned by a scanner head from a first position in the container which is at an angle relative to the vertical axis of the container. The scanner head is placed in a second position in the container at an angle relative to the vertical axis of the container and from the second position the scanner head scans the portions of the interior lining of the container which were not scanned during the first position scan. By comparing the scanning measurements of the lining from the first position scan and the second position scan after the container has been loaded and unloaded with an initial reference measurement of the lining the wear of the lining can be measured.
