Verfahren, Vorrichtung und Verwendung der Vorrichtung zur quantitativen Bestimmung der Konzentration oder Partikelgrößen einer Komponente eines heterogenen Stoffgemisches

The invention concerns a procedure and device for quantitative determination of number and size of particulate matter within a flowing media propagating along a flow channel whereby ultrasound is coupled into the flowing media and is at least partially reflected by the particulate matter. The detectable reflected ultrasound time signals form part of the quantitative evaluation process
