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.The invention relates to an ultrasonic flowmeter for measuring flow velocities in a measuring channel (3), which comprises an ultrasonic transducer (2) serving as transmitter and receiver. The ultrasonic flowmeter (1) has at least two reflectors (7, 8, 16), which are aligned so that the sound waves from the ultrasonic transducer (2) by the flowing fluid (4) back to the ultrasonic transducer (2) are passed.
