Claim Text:
1. An ultrasonic flow measuring device for ascertaining flow velocity, respectively volume flow, of a fluid, using a travel-time difference method, comprising: a measuring tube having a straight measuring tube axis; at least a first transducer for transmitting an acoustic signal; at least a second transducer for receiving the acoustic signal; and at least one reflection surface for reflecting the acoustic signal, wherein: said first transducer and said second transducer are arranged on the tube wall of said measuring tube in such a manner that they transmit, respectively receive, the acoustic signal inclined or perpendicularly to the flow direction of the fluid; the acoustic signal travels between said first transducer and said second transducer along a signal path, which includes a reflection on the at least one reflection surface; and in that the at least one reflection surface is embodied concavely in at least one preferential direction in the measuring tube; wherein at least one concavely embodied reflection surface is embodied as a component, which is releasably installed in said measuring tube.
