Annotation:

The article describes the studies of the statistical approach when analyzing measurement information and parameters of the technological process of measuring systems under operating conditions and methods applied for evaluating measurement results – an improved method of evaluating technological processes proposed by W. Shuhart is among them. The developed method expands the capabilities of the basic evaluation method and for the first time allows the most complete analysis, monitoring and setting of process parameters, allowing to obtain measurement information that compensates for the external factors affecting the accuracy of measurement values involved in calculating the amount of energy. The statistical approach application allows ensuring and maintaining technological processes at a stable level, guaranteeing reliable measurements by converters of level, mass, volume, density, temperature and pressure as part of measuring systems for determining the amount of energy of liquefied natural gas.
