Abstract:
A level sensing system and method for determining the level of a conductive material in a casting mold are disclosed, wherein the level sensing system a drive circuit and an inductive component disposed adjacent to the casting mold, and a position of the conductive material in the casting mold may be determined by a change in an electrical characteristic of the drive circuit.
