ABSTRACT:
A clamp-on ultrasonic flow measuring device for determining volume and/or mass flow rate of a medium in a containment. The clamp-on ultrasonic measuring device is of low temperature sensitivity. To this end, the coupling element, through which the ultrasonic measuring signals are coupled into, and/or out of, the containment, has at least two element portions, which are embodied and/or arranged in such a manner that the predetermined in-coupling angle into the containment and/or the predetermined out-coupling angle out of the containment are/is approximately constant over an extended temperature range.
