PROBLEM TO BE SOLVED: To speedily and accurately estimate the leakage locations, in a leak detection system in which a large number of gas sensors are arranged. SOLUTION: An output voltage of each sensor is converted into concentration to determine time derivatives of concentration. Leakage locations are estimated on a straight line 22 connecting sensors having large values for time differential coefficients. COPYRIGHT: (C)2009,JPO&INPIT
