dc.description.abstractUltrasonic flowmeter error caused by distortion of flow structure has been investigated in this paper. Minimum number of acoustic chordal paths of multi-channel ultrasonic flowmeter was determined that ensures the error caused by distortion of flow structure less than the specified limits ±0.3 %. The authors used Salami velocity function as a model of distortion of flow structure. Acoustic path configurations of ultrasonic flowmeter were determined using classical numerical methods of integration of Gauss-Jacobi. The authors improved the flow rate equation of ultrasonic flowmeter by introduction of calibration coefficient that was determined using symmetric component of Salami function.uk_UA
