Title: (EN) Ultrasound flow measurement method
Abstract:
(EN) The invention relates to a method and a device for ultrasound flow measurement for flowing media with a measuring tube (1), with at least two pairs of ultrasound transducers arranged on the measuring tube and each forming a measuring path (M1, M2, M3, M4, M5), with a transducer (2) determining the speeds of the medium along the measuring paths (M1, M2, M3, M4, M5) from the signals of the pairs of ultrasound transducers and with an adder (3) determining the flow rate of the medium from the speeds of the medium along the measuring paths (M1, M2, M3, M4, M5). The invention proposes a method and a device developed in such a manner that a Reynolds number meter (5) constantly determining the Reynolds number is provided, and a flow rate corrector (6) is connected to the adder (3) and the Reynolds number meter (5).
