Abstract

Die Erfindung bezieht sich auf einen Ultraschall-Durchflussmesser zur Messung von Strömungsgeschwindigkeiten in einem Messkanal (3), der einen als Sender und Empfänger dienenden Ultraschallwandler (2) umfasst. Der Ultraschall-Durchflussmesser (1) weist zumindest zwei Reflektoren (7, 8, 16) auf, die so ausgerichtet sind, dass die Schallwellen vom Ultraschallwandler (2) durch das strömende Fluid (4) wieder zurück zum UltraschallWandler (2) geleitet werden.
