Allen-Bradley DataSite™ RTU and Electronic Flow Meter

Oil and Gas Industry

OverviewWhen you need a rugged Remote Terminal Unit (RTU), the Allen-BradleyDataSite™ controller from Rockwell Automation is an excellent technology for service in harsh and extreme industrial environments likeoil, gas, pipeline, electrical and industrial combustion applications. It isideal for applications that require wide temperature ratings and lowpower consumption, and applications that are remote and powered bysolar cells or wind power. Electronic flow meter versions of DataSite incorporate AGA 3, AGA 7, and AGA 8 algorithms for computation of natural gas flow, making it well-suited for remote site natural gas well-head monitoring.

You also have the option to purchase the DataSiteas a configured panel in a rugged NEMA 4X enclosure, which can be wall or pipe-mounted. Takeadvantage of the standardized design with multipleoptions such as an operator interface, wireless radiomodems (three standard options, including antenna and cable accessories or the option to useyour own) and a 12V DC or 24V DC system configuration.

Help reduce your leadtime and engineering costs with our standardproduct. Program with industry leading RTU software, ISaGRAF, asoftware environment designed to facilitate the task of automationthroughout the life cycle of a system, from system design tocommissioning, operation, and maintenance. The developmentworkbench is the entry point for ISaGRAF and provides powerful, easy-to-use graphical and textual editors, such as docking toolbars,resizeable split windows, drag-and-drop and cut-and-paste.
