Abstract
A process and system for fluid distribution from a principal intelligence and fluid distribution center to multiple users through distributed intelligence sub-centers. Intelligence transmission from individual user valves and meters to the distributed intelligence sub-centers and from the distributed intelligence sub-centers to the principal intelligence and fluid distribution center is achieved in conjunction with the piping by means such as wires within the cavity, wires embedded in the structure of the piping, wires along the exterior of the piping, fiber optics, or acoustic, electromagnetic or optical methods through the piping itself. 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.
