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).
