Abstract

An ultrasonic flowmeter is provided with at least one measuring tube having at least one recess. Disposed in the recess are at least a first ultrasonic transducer and a second ultrasonic transducer, wherein the first ultrasonic transducer is designed as an ultrasonic transmitter and/or as an ultrasonic receiver and the second ultrasonic transducer is designed as an ultrasonic transmitter and/or as an ultrasonic receiver. Further disposed in the recess is at least one reflection surface. The first and second ultrasonic transducers are arranged on the measuring tube such that the measuring path between the first and the second ultrasonic transducers comprises at least one reflection at the reflecting surface. The provision of the reflection surface in the recess provides an ultrasonic flowmeter with which the flow profile can be easily measured, especially in the edge region.
