Abstract
A method of measuring the level of molten metal in a continuous casting m comprises inducing in the molten metal a magnetic field by a primary electrically energized coil and, by the relationship of this magnetic field to a pair of symmetrical secondary coils coaxial with the primary coil, inducing voltages in these secondary coils which are electrically connected in a circuit opposition so that the resultant voltage represents the level of the molten metal.
