Zusammenfassung:	In continuous casting, the level of molten steel 2 in mould 4 is detected by taking images of the free surface 5 with video camera 6, scanning lines substantially in parallel with the free surface. The video camera produces signals corresponding to images of the free surface and to those of background. The signals are converted into binary signals wherein the molten steel is represented by one level and the background by the other. The binary signals representing the molten steel are summed to obtain a total area of the molten steel. A predetermined area corresponding to the gravitational flow into the mould is subtracted from the total area to obtain the area of the free surface proportional to the level of the free surface.
