Opis:: In the paper intelligent compensation of flow errors, caused by profile distortion has been presented. This increases the accuracy of ultrasonic multipath meters used in such conditions. The goal of this intelligent correction consists in search of optimal layout and minimal sufficient quantity of chords in measurement transducer under different installation effects.

Opis:: Experimental results of air velocity profiles and Flow Averaging Tubes (FAT®) K-factor measured behind an elbow are presented in this paper. The pipeline diameter was D=150 mm, while the range of mean velocities w=9…30 m/s. Velocity profiles were determined both in the vertical and horizontal plane in the respective distances L/D of a pipeline from 3 to 18. In the places of the measured velocity profiles, three cross-sections of flow averaging tubes (circular, streamlined and two-profile) were placed to determine the characteristics of K-factor. Moreover, a fully automated test stand is presented in this paper. The completed experiment allows shortening the distance between an elbow and a flowmeter installation place and informing about the value of a correction factor, which can be used to minimize the measurement uncertainty of the air flow rate. It was stated that the horizontal plane is better to install a probe because of the velocity profile and better results of repeatability.
