Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Improvement of testing schemes for measuring instruments of the consumption of gas in operating conditions on the ural metrological center O.V. KRYUKOV Features and technical capability of introduction of the testing installations of new type providing exact measurement of a consumption of natural gas in operating conditions are presented. Tasks, technological processes of measurements and results of realization of three stages of projects of the metrological center are considered. Work of block diagrams of a technological part and the modern equipment taking into account an arrangement on a functioning gas pipeline on providing high rates of accuracy and reliability of measurements is analyzed. It is shown that creation of new technological stages of checking and means within the Ural metrological center is one of significant steps on a realization of Strategy of ensuring unity of measurements in Russia. Keywords: measuring instruments, testing scheme, metrological center, consumption of natural gas, unity of measurements. Contacts: E-mail: o.v.kryukov@mail.ru Pp. 24-31.
