Abstract

A system for measuring the interior of a hot glowing vessel (1) in a metal works with the aid of an electric distance measuring device (200) which is protected against radiant heat from the vessel and which performs a measuring operation with the aid of a light beam which is emitted from a light beam source and reflected back from the measuring point in approximately the same direction as that in which it was emitted. The distance measuring device is provided with an angle indicator for at least two mutually different directions and also includes a calculating device (24) which is provided with a memory and which functions to calculate the position of the vessel in relation to the distance measuring device. All measurements are calculated in a coordinate system related to the vessel. The internal surface dimensions of the vessel are calculated with the aid of measurements made on selected parts of the internal surface. The distance measuring device (200) is placed on a stand (2; 6) which can be moved along a predetermined movement path (7). On the basis of information stored in the memory (32, 36) relating to the extension of the path in relation to the vessel and the position of the distance measuring device on the path, the calculating device (24) calculates the position of the distance measuring device in relation to the vessel at each point along the path.
