GridBoss Gas Pressure Control System

The two controllers work in tandem to maintain the low pressure point within a specified deadband, thereby reducing average system pressure. In a typical municipal installation, many GridBoss™ district regulator controllers would be employed at regulator stations around a city to control gas pressure based on the time of day and temperature demand profiles derived from the GridBoss™ low pressure point controller.

GridManager™ User Interface

The GridManager™ provides customers with numerous software tools to get the gas pressure control system up and running quickly. These include step-by-step procedures for system creation, Intellution dynamos for screen building, pre-defined database formats for the GridBoss™ units, and tag name conventions. Sample data screens provided for region selection, region overview, district regulator station, low pressure point site, and detailed monitor and control pop-ups.

System reports are generated in an MS Access database with all available Access query and report capabilities. Sample reports are provided and include weekly pressure report, monthly pressure summary, and system status reports. Other system features include integrated context-sensitive help screens and application specification documentation.

The GridBoss™ Gas Pressure Control System was developed with the assistance of the Gas Research Institute and the Institute of Gas Technology.
