Abstract: The 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).

Abstract: The invention concerns and ultrasound flow rate measurement method by means of a measuring tube and at least two pairs of ultrasound transducers located on the measuring tube, in each case forming a measuring path, whereby the radial components of at least two measuring paths deviate from each other with respect to the axis of the measuring tube and in the case of which the measured value for the rate of flow of a flowing medium is determined from the velocity of the medium along at least two measuring paths. In accordance with the invention an ultrasound flow measuring method of this kind is further developed in that the eddy intensity in the medium is determined from the velocities of the medium along the measuring paths, the relation between angular momentum and axial momentum enters into the determination of the eddy intensity at least approximately, and the measured value for the rate of flow is corrected by means of the eddy intensity.
