Patent ID: 11359949

Abstract:
An ultrasonic flowmeter includes a measuring tube and first and second ultrasonic transducers. The first ultrasonic transducer is an ultrasonic transmitter and/or an ultrasonic receiver, and the second ultrasonic transducer is an ultrasonic transmitter and/or an ultrasonic receiver. The ultrasonic transducers are offset on the measuring tube such that the respective transmitter transmits an ultrasonic signal in the direction of flow or against the direction of flow, and the receiver receives the ultrasonic signal after at least three reflections. A course of the ultrasonic signal defines a signal path with first and second signal path sections. The number of sub-sections of the first signal path section corresponds to the number of sub-sections of the second signal path section. The signal path in the first signal path section has a first direction of rotation, and the signal path in the second signal path section has an opposite, second direction of rotation.
