Аннотация:The technique of ultrasonic flowrate measurement by multipath flowcells is presented and analysed. It is shown that the presence of flow asymmetry has an influence on the accuracy of quadrature integration as a basic tool for data processing in ultrasonic multipath spoolpieces. To obtain the metrological effectiveness of the multipath flowcells for the case of disturbed flows, full characterization and reconstruction of the flow velocity profile at each point of some cross-section of the transport channel is necessary. As the first stage, an implementation of Abel’s transform is suggested.
