Abstract: Todays modern natural gas infrastructure requires the need for natural gas utilities and pipelines to remotely control flow and pressure through control valves, regulators and actuated block valves to properly and safely control the gas flow to critical systems. For those new to the gas industry, much of this technology may seem overwhelming, and difficult to understand how commands from a gas control center are transferred to the field devices, and signals from end devices are relayed back to the control center. There are many factors that are used in the selection of these control devices so that proper operation and control is consistent, reliable and operates safely in the field. This paper outlines the basic techniques used to achieve these goals.
