Abstract: A clamp-on ultrasonic flowmeter includes pairs of ultrasonic transducers arranged on an exterior of a pipeline, and an electronic measuring/operating circuit for operating the transducers and for registering and evaluating measurement signals and for providing measured values of volume flow or flow velocity. The pairs are implemented as 1-traverse or 2-traverse pairs. One-traverse pairs are arranged on opposite sides of the pipeline, and 2-traverse pairs are arranged on a same side of the pipeline. At least three pairs are arranged on the pipeline and are distributed peripherally. Adjoining pairs of a number of pairs have an inner angle down to a minimum inner angle (MIA) between one another measured about a pipeline axis, which minimum inner angle obeys the following relationship:
MIA=360°/(T*N*F(T,N))
with T as number of traverses and F(T,N)=0.38+0.62*T+(0.048−0.01*T{circumflex over ( )}2)*(N−2){circumflex over ( )}2.-

Abstract: A measuring tube, especially a measuring tube for an ultrasonic, flow measuring device, which measuring tube has a measuring tube wall and at least in certain regions a basic form with rotational symmetry or polygonal cross section and a straight measuring tube axis. The measuring tube includes at least one functional area for positioning a reflector, on which an acoustic signal is reflected on a signal path, and the functional area is formed integrally from the measuring tube wall. The functional area defines in at least one sectional view a circular segment, which serves as support for a reflector or the functional areas has stops, whose distal ends define in at least one sectional view a circular segment, which serves as support for a reflector, as well as an ultrasonic, flow measuring device and a method for manufacture of a measuring tube.
