Measurement of hydraulic parameters of technological processes (fluid flow and pressure) is
one of the ways to achieve energy efficiency in various industries, including thermal, nuclear and
hydraulic power plants with automated control of power units and individual power plants (pumps,
turbines, heat exchangers and other). The aim of the research is to analyze the metrological characteristics of means for measuring hydraulic parameters for the tasks of energy-saving control of
equipment of thermal, nuclear and hydraulic power plants and to determine the methods and means
of measurement that allow providing practical implementation of the principles of energy-saving
management. Among the large number of flow measurement methods, a special place is occupied
by flow measurement systems based on variable pressure drop. The article shows the main directions in which research is being carried out to improve and increase the efficiency of methods for
measuring fluid flow. A quantitative analysis was conducted to examine the distribution of the variable pressure drop method and the corresponding measuring systems. The study focused on evaluating the market for flow measuring systems, specifically analyzing its distribution patterns.
This research investigates the distribution of traditional flow measurement technologies
within the fleet of flow meters and systems, comprising approximately half of the total. A comprehensive analysis of fluid flow and pressure measurement methods is conducted, with a focus on
identifying the most promising methods for application in energy-saving control of power plant installations.
The study includes a concise evaluation of domestic and foreign flow meters of various
types, highlighting their main metrological characteristics. The conclusion is made about the expediency of using various types of measuring systems in information-measuring complexes of automated control systems for power units at power plants.
