Abstract
An apparatus for measuring the level of molten metal in the oscillating mold of a continuous casting machine in operation by an eddy-current type distance measuring device. The oscillation signal component due to the oscillation of the mold is extracted from the output signal of the distance measuring device and the detection sensitivity of the distance measuring device is compensated and controlled so as to maintain the amplitude value of the oscillation signal component at a constant value thereby linearizing the molten metal surface level versus output characteristic.
