Abstract: As early as 1966, Tennessee Gas Pipeline Company was investigating a telemetering and control system to benefit our Gas Control Facilities at Hockley, Texas. Field hardware suitable for such a system was not available at the time. As suitable components became available, the components were evaluated by company personnel and in 1971 steps toward actual installation of a Data Acquisition and Control System (DAC) were begun. The primary purpose of the DAC System is to give the dispatcher the latest up-to-date information about Pipeline operating conditions. Until this time, dispatchers obtained line pressures at set intervals by telephone and calculated volumes of gas bought and sold during the previous day for dispatching purposes. This meant that the dispatcher was using historical data to operate the pipeline system now.
