| 摘要 |
The invention relates to a measuring pipe, in particular for an ultrasonic flow meter, said measuring pipe (2) having a measuring pipe wall (11) and a basic shape with a rotationally symmetrical or polygonal cross-section at least in some regions and a straight measuring pipe axis (M). The measuring pipe (2) has at least one functional surface for positioning a reflector on which an acoustic signal on a signal path (8) is reflected, and the functional surface is integrally formed from the measuring pipe wall. The invention is characterized in that the functional surface defines a circular segment in at least one sectional view, said circular segment being used to support a reflector, or the functional surface has stops with distal ends which define a circular segment in at least one sectional view, said circular segment being used to support a reflector. The invention also relates to an ultrasonic flow meter and a method for producing a measuring pipe. |
