Essay

Dissertation is devoted to the development and implementation in practice of scientific and methodological approaches, and legal documents of management system of measurements at the metering centers in the transmission of gas from its suppliers to consumers. The procedural and systematic approach to manage risk of getting unauthentic results on the stage of design and operation of measuring equipment is theoretically justified and applied. The model of process control system of measuring the volume is created with statistical methods for quality control of measurement results as informative parameters of this system. Using cause and effect diagram are identified risks associated with potential failures of process measurement to use preventive and corrective actions before a failure occur. Here is invested and justified the process measurement variability, which is the source of changing the work environment and instability of standards in the transmission unit. Here are established mathematical dependences of gas measurement errors by their metrological validation in the air environment. Is developed technology of FMEA-analysis by adopting the Goldratt's theory of constraints and are constructed cause and effect chains of undesirable defects of the rotary gas meters construction, eliminating of which at the stage of designing of the meters raise the quality and reliability of that meters. Are developed and put into practice two regulations for the effective implementation of corrective and preventive actions of measurements of gas management system
