57	Abstract	AB	Es gibt eine Vorrichtung, bei der eine Meßkammer 2 von einem Gehäuse 1 begrenzt ist und in der Meßkammer ein flügelartiger Drehkolben 5 drehbar ist. Dabei ist es erwünscht, wenn die Vorrichtung an die Partikelgröße der Schlämme und/oder die Flockengröße der Schlamm/Flockmittel-Mischung in einem verbesserten Umfang anpaßbar ist. Dies ist erreicht, indem ein von dem Drehkolben 5 begrenzter Durchgangsspalt 21 in der Spaltweite mittels eines außen am Gehäuse 16 vorgesehenen Stellglieds 25 in Anpassung an Ergebnisse von Laboruntersuchungen verstellbar ist. Konstruktiv gehört zu der Vorrichtung die Verstellbarkeit der Durchgangsspalt-Spaltweite mittels des außen am Gehäuse vorgesehenen Stellglieds. Betriebsmäßig gehören zu der Vorrichtung Laborversuche an dem Schlamm und der Schlamm/Flockmittel-Mischung, die Aufschluß über die Partikelgröße des Schlamms, die Flockengröße und der Schlamm/Flockmittel-Mischung und die Trübheit/Reinheit eines daraus gewonnen Filtrats geben.
