Abstract: A measuring device for measuring flow and/or composition of a measured medium in a pipe or tube by registering an ultrasonic measurement signal includes a measurement transmitter and a connection adapter for mechanical securement of the measurement transmitter on the pipe or tube, in which the connection adapter has a longitudinal axis and the measuring device includes a measuring transducer element and at least one metal hose, wherein at least one signal transmission cable is arranged in the metal hose for signal transmission between the measurement transmitter and a sensor element, and wherein the metal hose mechanically connects the measuring transducer element with the connection adapter.

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.-
