Scientists have developed a robot that detects gas leakage from pipes Bashny.Net

Self-propelled robotic device can pass through the pipes more accurately and quickly detecting gas leakage, in comparison with existing methods.

Researchers at mit and the University of petroleum and minerals (KFUPM) in Saudi Arabia have devised a robotic system that can detect leaks at a rapid pace and with high precision, sensing a large pressure change in the places of leakage. The concept was presented at two international conferences. One of the authors of the invention Dimitrios Chatzigeorgiou says: "This new system can detect leaks the size of 1-2 mm, and at a relatively low pressure. We have proved that the concept works." In addition to looking for leaks of "blue" fuel, the new technology can be applied in water supply networks and oil pipelines.

The new device consists of two parts: a small robot, with wheels to propel it through pipes and a membrane that forms a seal across the width of the pipe. When leakage occurs, the liquid distorts the membrane, pulling it slightly to the side of the leak. This distortion can be detected using the force sensors and the information is sent via a wireless connection. According to the developers, these devices can be introduced into the system of pipes and left there indefinitely, conducting automatic, nonstop monitoring of the system.

Co-author Professor Kamal Youcef-Toomey is convinced: "This technology is designed for an unambiguous and reliable sensing of very small leaks that often go unnoticed over a long period of time." Currently, the system requires a fairly uniform pipe diameter, but the researchers are working on a version which will have more flexibility to deal with variations caused by the damage, obstructions or build-up inside the pipes.
