These are the main components of the MilliWave Viscometer, developed in part by Pacific Northwest National Laboratory. This technology is a high-temperature viscosity measurement technology for process monitoring of hot molten materials such as in glass manufacture and metals refining. The refractory waveguides are to the left. The millimeter-wave electronics package is shown in the upper right and a ceramic waveguide at a temperature of 1200 degrees C is shown in the lower right. Developed by researchers at Massachusetts Institute of Technology, Pacific Northwest National Laboratory, and Savannah River Technology Center, the MilliWave Viscometer won a 2001 R&D 100 Award.

Date of Image/Photo: August 6, 2001
Background: The MilliWave Viscometer is a high-temperature viscosity measurement technology for process monitoring of hot molten materials such as in glass manufacture and metals refining. It fills a need for a high-temperature on-line viscosity sensor that makes possible real-time process control in the manufacture of glass, metals, and other melter-produced materials. It is the only viscosity measurement technology that uses millimeter-wave electromagnetic radiation to probe the movement of liquids.
