Abstract

PURPOSE: To make it possible to detect the level of molten metal easily with high precision and high sensitivity, by detecting the level by vertical fluctuations of the inflection part of a light picture obtained when a longitudinally long luminous flux is projected upon the wall surface of a container and the surface of the molten metal.
CONSTITUTION: Internal wall 1b of container 1 and the surface of molten metal 2 are irradiated simultaneously with a longitudinally long luminous flux from projector 5 and the irradiation light image is displayed on TV monitor 14 via receiver 6 installed in the direction of the optical axis of reflection. This light image consists of vertial part P1' and inflection part P2' and according to fluctuations of the level of molten metal 2, inflection part P2' fluctuates, so that the level of the molten metal can be detected easily with high precision and high sensitivity.
