Abstract
The article provides the analysis of the rate of extraction and consumption of natural gas in the world for the last decades. In this regard, great significance flow meters and counters of liquids and gases. Almost none of contemporary production is not without these devices. According to worldwide operates about 15 million of measuring flow rate and volume of substances. This raises another more complex and important task - development of reference installation of natural gas consumption, which reproduces and ensure the transfer of the size of units of gas consumption when operating in the trunk pipeline pressures. Presents metrological characteristics and technical possibilities of existing major reference installations of natural gas consumption in the world Pigsar, EuroLoop, COKE, CESAM, NEL, ARMZ, hush. In this article the comparative analysis of the existing gas flow standards on following indicators: range absolute pressure ; stability absolute pressure ; the range of pipe diameters ; the maximum length of the measuring pipeline; the range of created expenditures; maximum uncertainty of measurement of mass flow rate of the complex. Each of the units has its own advantages and disadvantages. Therefore, when solving the task of creating such a gas flow standards, developers are encouraged to consider the advantages and disadvantages of existing facilities to ensure high precision, functionality and stability of the parameters influencing the process of reproduction and transfer of units of gas consumption. The analysis of these characteristics, and compared their technical capabilities are a few recommendations, which are formed in the form of conclusions.
