Abstract: An ultrasonic meter for recording a through-flow rate of a fluid has a fluid inlet, a fluid outlet, and a flow channel connecting the inlet to the outlet. The flow channel has a measurement region which extends in a straight line in a flow direction. Between the measurement region and the fluid outlet, there is arranged a reflection element which is flowed around by the fluid and by which an ultrasonic signal is reflected into the measurement region. Between the measurement region and the reflection element, there is arranged a changeover region of the flow channel. In the changeover region a spacing between a central straight line of the measurement region and the side wall enlarges. The changeover region has, in the circumferential direction of the flow channel, several circumferential sections in which the enlargement of the spacing between the central straight line and the side wall takes place.
