“…The results showed that the generalized model can reduce the sensitivity of the flowmeters to flow field deviations, with a minimum mean relative error of 1.64% under symmetric and asymmetric flow fields. A recent study by the same authors introduced a multipath ultrasonic flowmeter that utilized phased array transducers and numerical integration [48]. The performance of the flowmeter was studied for different flow fields, and the impact of various factors, such as the number of paths, beam angle, and installation angle, was analyzed.…”

This study investigates the impact of changes in velocity profiles on the measurement inaccuracies of gas flow streams detected by an ultrasonic flowmeter. The cross-sectional velocity profile was influenced by the downhill flow rate, causing variations in the shape factor coefficient. The flowmeter processing equation should consider the factor of shape coefficient variations. Consideration for these variations can result in errors in the measurement of the flow stream. The processing equation assumes a single, constant value for the shape factor coefficient, which can lead to inaccuracies. This article covers the inaccuracies of the transit-time ultrasonic flowmeter caused by a change in the velocity profile of the flowing gas, such as air. A realistic flow system was established with measured flow rates ranging from 43 m3/h to 225 m3/h. The findings of this study can serve as a valuable reference for the design and implementation of more accurate and efficient flow measurement systems that can enhance process efficiency.
