Abstract

Vorrichtung zur Förderung von Flüssigkeiten, insbesondere zur Abgabe von Flüssigkeiten aus Tankwagen, mit einer Verdrängerpumpe (10) in eine Abgabeleitung (18), die von einem Elektromotor (22) angetrieben ist, einer Steuervorrichtung (24) für den Elektromotor (22) und einer Vorrichtung (28) zur Bestimmung von Gasanteilen in der Flüssigkeitsströmung, wobei am Gehäuse der Pumpe (10) ein Körperschallaufnehmer (26) angeordnet ist, der mit einer Auswertevorrichtung (28) für den gemessenen Körperschall des Pumpengehäuses verbunden ist und der ein Signal auf die Steuervorrichtung (24) gibt, wenn eine Veränderung des Körperschalls gemessen wird.
