Abstract
A method detects a level of a melt contained by an oscillating mold. The method includes a) sensing radiation interacted with the melt and generating from the sensed radiation radiation signals, such that the generated radiation signals are varied by the mold oscillation, b) determining a radiation signal variation of the generated radiation signals, c) determining an oscillation deflection variation of the oscillating mold, and d) determining from the determined oscillation deflection variation and the determined radiation signal variation, the level of the melt.
