Abstract
The article discusses the investigation of the digital signal processing methods efficiency in ultrasonic flowmeters. Using digital signal processing allows to increase the accuracy in the propagation times difference measuring of ultrasonic signals-the main informative parameter of an ultrasonic flowmeter and to reduce the measurement error. Analytic expressions are obtained that allow one to evaluate the effect of the probing signals parameters and the digital signal processing correlation methods parameters on the effectiveness of their application in ultrasonic flowmeter. The studies were carried out as part of the preparation of methodological materials for developed laboratory work on the course “Fluid and gas flow measurement”.
