Abstract
Abstract A process and system for fluid distribution from a principal intelligence and fluid distribution center to multiple users through a plurality of distributed intelligence sub-centers. Each distributed intelligence sub-center has intelligence computing, analyzing, decision making, and direction capability to provide control for its portion of the system. The process and apparatus of this invention provides flow control, leak detection, pipe condition assessment, user meter readings, pipeline locator signals, robot control, and pipeline repair and cleaning. The process provides a total system approach providing improved safety and reduced operating costs and is particularly suited for underground distribution of natural gas services.
