Patent ID: 8560252

Claim:
A coupling element of a sensor of an ultrasonic, flow measuring device, comprising: at least three rods having, in each case, a first rod end and a second rod end, wherein said at least three rods, in each case, have on their respective first ends first end faces, which, in each case, can be acoustically coupled with a sound-emitting and/or sound-receiving area of an ultrasonic transducer element, wherein: said respective first end faces of said at least three rods together form a first coupling surface of the coupling element; said at least three rods, in each case, have on their respective second ends second end faces, which form a second coupling surface of the coupling element; and said at least three rods, in each case, have a first rod cross section, which is different in shape and/or size from a respective second rod cross section.
