Abstract
Methods and systems for determining density or density gradient of molten foamed glass in a glass melter, an apparatus downstream of a glass melter, or both. A molten foamed glass is generated having molten glass and bubbles entrained therein and/or a layer of glass foam on a top surface thereof in a melter. At least a portion of the molten foamed glass is transferred into an apparatus positioned downstream of the melter, and the density or density gradient of the molten foamed glass in the melter or downstream apparatus is determined as a function of distance from a structural feature of the melter or downstream apparatus, or both, using one or more electromagnetic (EM) wave-based sensors.
