Abstract :
Detection of gas bubbles is an important indicator of the process quality in the industrial applications. Gas bubbles in the liquid not only falsify the measurement of the flow rate, but indicate problems like leakage, cavitations, reactions, boiling, etc. Based on electric field simulations and measurement in the flow laboratory, a physical device model has been developed. This paper presents the wavelet transform-based detection of gas bubbles. Application results based on the acquired signals with and without bubbles in liquid flow are presented.
