A halogen light source (transmitter) directs a light beam onto the glass surface in the furnace. The light beam, which is reflected from the surface of the glass, is picked up by a receiver and evaluated electronically. Changes in the level of the glass give rise to parallel shifts of the reflected light beam which are used as parameters for the assessment of the level.
