A fluid measuring arrangement with a flow channel for a fluid to be measured having at least two areas of an outer wall forming waveguide parts for surface acoustic waves. The waveguide parts are spaced apart from each other along the circumference of the flow channel. A first and/or a second signal converter is arranged at each waveguide part, wherein at least two first signal converters arranged on different waveguide parts or two second signal converters arranged on different waveguide parts are spaced with respect to each other in the axial direction of the flow channel.

A fluid meter has a measuring tube which has a fluid channel allowing a fluid (F) to flow through and which has a measuring section in which at least one area of a measuring tube wall is formed as a waveguide for surface acoustic waves, which forms an interface with the fluid (F), and at least one transmitter for exciting acoustic waves in the waveguide as well as at least one receiver for receiving acoustic waves from the waveguide, wherein acoustic waves excited by the transmitter can propagate through the fluid (F) as a bulk wave (V) and the bulk wave (V) has at least one reflection point (IP) on the measuring tube wall. The measuring tube wall has a first wall thickness (T) in the area of the transmitter and in the area of the receiver and has a second wall thickness (T) which differs from the first wall thickness (T) in the area of all reflection points (IP) of the bulk wave (V).

A measuring device with a fluid module is proposed, which comprises a measuring tube through which a fluid can flow and at least one acoustic measuring unit. The at least one acoustic measuring unit comprises at least one transmitter, at least one receiver as well as at least one waveguide. The measuring tube has at least one measuring section with a substantially angular internal cross section and at least one connecting section with a non-angular internal cross section, wherein the measuring tube has at least one transition section, which extends between the measuring section and the connecting section. The transition section has an internal cross section identical to the internal cross section of the measuring section at an end allocated to the measuring section and further an internal cross section identical to the internal cross section of the connecting section at an end allocated to the connecting section. Furthermore, a fluidic system is described.
