Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb eines Durchflussmessgerätes, gemäss Oberbegriff des Patentanspruches 1. Um hierbei zu erreichen, dass eine optimale Signalerzeugung an alle Gegebenheiten ermöglich ist, ist erfindungsgemäss vorgeschlagen, dass in der Signalverarbeitung der Durchflussmesseinrichtung während der Messphase automatisch eine aktuelle Signal/Rauschverhältnis-Ermittlung durchgeführt wird, und dass abhängig vom Ergebnis die dem Messystem zugeführte Energie angepasst wird.
