Abstract
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).
