Abstract: An ultrasonic flow meter comprising: a measurement pipe, which has a measurement pipe wall, at least in some parts a basic shape having a rotationally symmetric or polygonal cross-section, and a straight measurement pipe axis; a transmitter for transmitting an acoustic signal on a first signal path; and a receiver for receiving the acoustic signal on the first signal path. The measurement pipe has a plurality of reflection surfaces, by which the acoustic signal on the first signal path is reflected multiple times, and wherein the reflection surfaces are integrally formed from the measurement pipe wall, the reflection surfaces for reflecting the acoustic signal being designed in such a way that one or more of the reflection surfaces at least partially protrude into the basic shape of the measurement pipe and one or more of the reflection surfaces project outward at least from the basic shape of the measurement pipe.

Abstract: A magneto-inductive flow measuring device (1) comprising a measuring tube (2) on which a magnet system and two or more measuring electrodes (3) are arranged and/or secured, wherein the measuring tube (2) has in- and outlet regions (11, 12) with a first cross section and wherein the measuring tube (2) has between the in- and outlet regions (11, 12) a middle segment (10), which has a second cross section, wherein the measuring electrodes (3) are arranged in the middle segment (10) of the measuring tube (2), wherein the middle segment (10) at least in the region of the measuring electrodes (3) is surrounded by a tube holder (15), which guards against cross-sectional deformation of the second cross section.

Abstract: A magneto-inductive flow measuring device comprising a measuring tube on which a magnet system and two or more measuring electrodes are arranged and/or secured. The measuring tube has in- and outlet regions with a first cross section and the measuring tube has between the in- and outlet regions a middle segment, which has a second cross section. The measuring electrodes are arranged in the middle segment of the measuring tube and the middle segment at least in the region of the measuring electrodes is surrounded by a tube holder, which guards against cross-sectional deformation of the second cross section.
