Method of regulating the viscosity of a mixture comprising at least two components having different viscosities

Abstract

The invention relates to a method of regulating the viscosity of a mixture (125; 210) comprising at least two components having different viscosities, which comprises the steps: (a) determination of the viscosity (132; 222) of the mixture (125; 210) by means of ultrasound measurements, (b) standardization of the viscosity determined (132; 222) to standard conditions, (c) comparison of the standardized viscosity (14) with a prescribed intended value (134; 224), (d) adjustment of the viscosity of the mixture (125; 210) by increasing or decreasing the proportion of at least one component of the mixture, where the ultrasound measurements in step (a) are carried out at or in a line conveying the mixture or in a vessel.
