In addition to the "simple" recording of volume flows or filling levels, acoustic measuring methods are successfully used for the analysis of a wide variety of material systems. Adapted algorithms enable, among other things, the calculation of the density of fluids, the quantification of disperse phases (particles, air bubbles) or the detection of deposits and corrosion in the pipe systems. Those parameters of a liquid or gaseous dispersion are important for processes in complex liquids, e.g. granulation by spray drying from the liquid phase, which are decisive for function, quality and sustainable performance. These parameters, which are particularly critical for efficiency and long-term stability, are not monitored completely yet.
This project addresses this problem by applying an innovative monitoring technology based on non-invasive acoustic measurements. The continuous recording and monitoring should provide a significant procedural and economic added value.
