The transducer ( 1 ) has at least one at least temporarily vibrating flow tube ( 101 ) of predeterminable lumen for conducting a fluid. The flow tube ( 101 ) communicates with a connected pipe via an inlet tube section ( 103 ), ending in an inlet end, and an outlet tube section ( 104 ), ending in an outlet end, and in operation performs flexural vibrations about an axis of vibration joining the inlet and outlet ends. The flow tube ( 101 ) has at least one arcuate tube section ( 101 c) of predeterminable three-dimensional shape which adjoins a straight tube segment ( 101 a) on the inlet side and a straight tube segment ( 101 b) on the outlet side. At least one stiffening element ( 111, 112 ) is fixed directly on or in close proximity to the arcuate tube segment ( 101 c) to stabilize the three-dimensional shape. By means of the at least one stiffening element ( 111, 112 ), the cross sensitivity of the transducer ( 1 ) is greatly reduced, so that cross talks from pressure to mass flow signals are minimized and the accuracy of the transducer is improved.
