Torsional Waveguide Sensor for Molten Materials

Viscosity of the molten glass is a key variable in determining the quality of the final glass product. At low viscosities the melt can be highly corrosive. At high viscosities the melter can become plugged. “Melt viscosity is the most important processing property; it controls processing rate, product homogeneity, and heat transfer within the molten glass [1]. “ Thus, the viscosity is an important parameter which can be used by the vitrification industry for the processing of waste material and by the glass industry for production of high quality glass products. The major problem in measuring the viscosity of the molten waste product is the extremely hot and corrosive environment
