Abstract

Bei einem Durchflussmessgerät mit Verdrängerzähler (1) weist ein parallel geschalteter Druckdifferenz-Aufnehmer (3) einen Bypasskanal (8) auf, der bei an seinem Maximal-Hubanschlag (9) anliegendem Kolben (7) eine Verbindung zwischen Zu- und Abströmseite (4, 5) freigibt. Im Bypasskanal (8) ist eine Rückschlagsperre (11) angeordnet, welche den Rückfluss von Abström- zu Zuströmseite (5, 4) unterbindet und damit eine rein druckbedingte Rückführung des Kolbens (7) ermöglicht.
