Beschreibung
Zusammenfassung:	An ultrasonic flowmeter includes a measuring tube, a first transducer pair including first and second ultrasonic transducers, and a second transducer pair including third and fourth ultrasonic transducers. Each ultrasonic transducer is an ultrasonic transmitter and/or an ultrasonic receiver. The first transducer pair is on the measuring tube offset such that the respective transmitter transmits an ultrasonic signal in or against the direction of flow, and the receiver receives the ultrasonic signal. A course of the ultrasonic signal between the first and second ultrasonic transducers defines a first signal path. The second transducer pair is on the measuring tube offset such that the respective transmitter transmits an ultrasonic signal in or against the direction of flow. The receiver receives the ultrasonic signal transmitted by the transmitter. A course of the ultrasonic signal between the third and fourth ultrasonic transducers defines a second signal path.
