Leak detection on gas pipeline with the distributed fiber-optic sensing technology |
| |
Abstract: | The theory model of leak detection system and experimental system in gas pipeline based on the principle of Sagnac fiber optic interferometer is summarized.The function of this system was also analyzed in theory and studied in experiment.The result of the experiment accorded with the theory analysis, which shows that it is realizable to detect and position the leak of the gas pipeline with this system. |
