The subject of the article concerns the measurement of flow streams with disturbed velocity distribution by the means of elbow flowmeter. The velocity disturbances were forced by a different setting of the aperture located at the inlet to the installation. In the article, flow coefficients for the elbow flowmeter for exemplary disturbances of velocity distribution were determined and deviations in relation to the flow without disturbances were calculated. For the exemplary disturbance, numerical calculations were performed, the results of which were compared with the actual results of the experiment.
