Zivenko O. Improvement of the polymetric computerized systems for measurements of technological liquids.

Subject matter of the study: technological liquids measurement processes. Aim of the research - the improvement of the polymetric measurement systems for operative measurement of characteristics of various liquid media, aimed at increasing the number of simultaneously measured characteristics using one sensor. Methods of research: mathematical modeling, experimental study, statistics and pattern recognition methods, data mining methods. Theoretical, practical results and novelty: the method of polymetric measurements of liquids characteristics improved by considering the combined effect of the measured characteristics of liquid media on polymetric signal; the method of reducing the temperature drift of the stroboscopic converter is proposed and implemented; The empirical dependence of the complex dielectric constant and the parameters of polymetric signal from the measured characteristics of a number of liquids; equations which link the dielectric permittivity, parameters of the polymetric signal with the characteristics of the controllable liquid obtained; the method of identification of a controlled liquid further developed. The results of the research implemented in the educational process of the National University of Shipbuilding, as well as in the activities of LLC "AMICO". Application areas: information-measuring systems and process control systems.
