ABSTRACT:
A method of and apparatus for detecting the level of molten glass in a glass melting furnace comprising transmitting an electromagnetic wave towards the surface of the molten glass, detecting the electromagnetic wave reflected from the surface of the molten glass, determining the amount of time elapsed from the transmission of the electromagnetic wave to the detection of the reflected electromagnetic wave, and generating a signal responsive to the amount of elapsed time as an indication of the level of molten glass in the furnace.
