Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Messung der Größen von in einem einer Leitung (3) folgenden Fluidstrom (2) dispergierten Partikeln, wobei dem der Leitung (3) folgenden Fluid-Partikel-Strom eine akustische Schwingung als Erregerschwingung aufgeprägt wird und eine Antwortschwingung der Partikel auf die Erregerschwingung gemessen wird, und wobei zur Ermittlung der Größen der Partikel eine Auswertung durch Vergleich der Erregerschwingung und der Antwortschwingung hinsichtlich Schwinggeschwindigkeit, Schwingungsamplitude und/oder Phasenverschiebung erfolgt. Ferner betrifft die Erfindung eine Anlage zur Messung der Größen von in einem einer Leitung (3) folgenden Fluidstrom dispergierten Partikeln, enthaltend: Erregereinrichtungen (E), um dem der Leitung (3) folgenden Fluid-Partikel-Strom eine akustische Schwingung als Erregerschwingung aufzuprägen, Detektoreinrichtungen (D), um eine Antwortschwingung der Partikel auf die Erregerschwingung zu messen, und Verarbeitungseinrichtungen (V) zur Ermittlung der Größen der Partikel durch Vergleich der Erregerschwingung und der Antwortschwingung hinsichtlich Schwinggeschwindigkeit, Schwingungsamplitude und/oder Phasenverschiebung.
