PCT No. PCT/EP96/05082 Sec. 371 Date Sep. 15, 1997 Sec. 102(e) Date Sep. 15, 1997 PCT Filed Nov. 18, 1996 PCT Pub. No. WO97/19326 PCT Pub. Date May 29, 1997The invention concerns a method and a device for ultrasound measurement of the flow of flowing media with a measuring tube (1), with at least two pairs of ultrasound transducers arranged on the measuring tube, each forming a measuring path (M1,M2,M3,M4,M5), with a transducer (2) determining the velocities of the medium along the measuring paths (M1,M2,M3,M4,M5) from the signals of the pair of ultrasound transducers and with an adder (3) determining the flow quantity of the medium from the velocities of the medium along the measuring paths (M1,M2,M3,M4,M5). According to the invention, such a method and such a device are designed with a Reynolds' number meter (5) that determines the Reynolds' number constantly and a flow-quantity corrector (6) connected to the adder (3) and the Reynolds' meter (5).
