The Employment of "PRIME GROUP" Company’s Engineering Solutions for Designing Custody Gas Transfer Meters

The most accurate assessment of consumed gas is considered to be the basics of efficient gas supply, thus emphasizing the importance of flow metering accuracy. 

However, the present-day Russian system of keeping a gas distribution and consumption record does not entirely meet current requirements. Only 10 percent of metering systems used by industrial and residential customers are equipped with evaluators, which provide automatic metering and transmitting of the obtained data.

To improve metering efficiency, decrease the disbalance level, and to simplify customer account settlements, Gazprom's and Mezhregiongaz' management approved a standard project to design an automated system for custody gas transfer metering. Within the project framework, by joint efforts of Giprogazcentr and PRIME GROUP companies, "The Uniform Technical Solutions for Metering Systems Used by Gas-Distributing Stations and Industrial Consumers" have been devised. The "Uniform Solutions" provide requirements and recommendations for the development of metering systems in both new and upgraded custody transfer meters used at gas-distributing stations and industrial gas consumers.

In 2006, on the request by Vladimirregiongaz, a regional gas company, PRIME GROUP company prepared several projects for custody transfer meters to be used by industrial gas consumers in the Vladimir region. While preparing the project and working documentation, the company used the requirements listed in the "Uniform Solutions", including the structure of a metering system, metrological support, software and dataware, electric power supply, etc.
Project solutions ensure gas flow metering by means of either the alternate pressure method or with the help of a turbine gas meter. The state-of-the-art metering systems Superflow-21V and SG-EK, as well as Yokogawa-made high-precision sensors functioning as pressure transducers were used to design transfer meters.

PRIME GROUP's operating experience proved that for the purposes of custody gas transfer meters design, "The Uniform Solutions" help finding the best solutions, which comply with current requirements of domestic and foreign instrument-making industry and  meet  present operating standards.
