Application of Smartball Drifting Leak Detection System in Oil Pipeline

Smartball drifting leak detection system is composed of host,smartball.voice receiver(SBR)and receiver(AGM).The systems working principle is that the voice sensor integrated in it is to used to collect the low-frequency sound wave signals of pipe leakage.Because the magnitude of the signal is proportional to the velocity of leakage rate,therefore the leakage position will be determined,and through AGM of built-in GPS module installed above pipeline,leak positioning accuracy is effectively improved.On September 15th.2009.the Smartball system was applied in Zhong Zaohuo-Golmud Section of Huatugou-Golmud Oil Pipeline.A leak hole was found at a distance of 70 499 m from the transmitting terminal of Smartball system,appearing a 0.5L/min of leakage rate.Verification on the detection results and actual position of pipeline leak showed that positioning error was only 2 m.It has been found that this system could effectively detect and locate the tiny leakage in pipeline with high adaptability.high detection precision,easy to use and high efficiency.
