Abstract

Bei einem Durchflussmessgerät, mit einem Verdrängerzähler (1), dem in einer Umgehungsleitung (2) ein Druckdifferenz-Aufnehmer (3) parallel geschaltet ist, wobei ein mit dem Verdrängerzähler (1) drehverbundener Motor (M) abhängig von einem vom Druckdifferenz- Aufnehmer (3) festgestellten Differenzdruck zwischen Zu- und Abströmseite (4, 5) des Verdrängerzählers (1) zum stetigen Differenzdruck-Ausgleich angesteuert ist, wobei der Druckdifferenz- Aufnehmer (3) einen in einem Zylinderbereich (6) der Umgehungsleitung (2) frei beweglichen Kolben (7) aufweist, wird die durch den Differenzdruck bedingte Auslenkung (X) des Kolbens (7) durch einen Magnetsensor (10) gemessen und ein entsprechendes Sensorsignal (S) erzeugt welches über eine Regeleinheit (11) zu einer Drehzahlanpassung des Motors (M) des Verdrängerzählers (1) verwendet wird.
