Abstract
The level of a metallic bath, e.g. of an iron melt in an ingot mold, is determined by recurrent electro-optical scanning of the interior of the vessel along a narrow vertical strip zone. The output signals of the scanner are processed in an arithmetic unit which averages successive readings, to compensate for fluctuations, and may also receive a corrective signal in order to offset periodic level changes due to an intentional rocking of the vessel. The arithmetic unit may work into a visual indicator and into a controller adjusting the rate of inflow and/or withdrawal to maintain the bath level substantially constant.
