Abstract
In a molten metal surface level detection system, the use of conventional detector means is eliminated and, instead, an ITV camera is provided at an appropriate place where it is neither thermally affected by the molten metal surface portion nor obstructs the site jobs and the molten metal surface portion is photographed by said ITV camera along a direction permitting the surveillance of the level of the molten metal surface and, then, the thus photographed image of the molten metal surface portion is processed in a suitable manner for accurately and reliably detecting the surface level thereof.
