A feasibility study to examine the equipment and methodology to use the sound of gas flow through a valve to confirm the exact position of critical valves in gas distribution systems. Field tests, using acoustics and an innovative tool delivery system proved the concept and highlighted the feasibility of combining acoustic and visual methods to identify the position of ball, gate and plug valves used in various applications in the gas distribution system. More work is planned to expand the program to other users, incorporate feedback, ruggedize the system, and make it field portable prior to commercialization.

Valve testing is a regular part of a pipeline operations and safety program. This technology ensures that the positioning of the valve during testing is as indicated by visual assessment. This technology would improve the ability to conduct a thorough inspection.

Increased Safety - This technology increases safety by providing a means of performing the inspection under live conditions while ensuring that the valve functions properly through its rated range of application.
