Accurate measurement and regulation of viscosity of liquids, especially molten glass, involves control of temperature based on viscosity measurements using electromagnetic field generator

摘要

In apparatus for measuring and regulating the viscosity of liquids (A), having a device (3) for determining the viscosity (and/or correlated parameter(s)) of a portion (5) of (A) and a regulator (4) for the temperature of the portion, the difference between the measured viscosity (and/or correlated parameter(s)) of the portion and a reference value is determined, the temperature of the portion is controlled utilizing the determined difference and the temperature regulator (4) includes a device for producing an electromagnetic field. An independent claim is included for a corresponding viscosity measuring and regulating process.
