A system includes a first gas sensor [ 110] to detect a first concentration of a predetermined gas and to determine a first rate of change in the first concentration over a time interval. A second gas sensor [ 115] detects a second concentration of the predetermined gas and determines a second rate of change in the second concentration over the time interval. A third gas sensor [ 120] detects a third concentration of the predetermined gas and determines a third rate of change in the third concentration over the time interval. The first, second, and third gas sensors each have a known location. At least one processing device [ 510] (a) determines respective distances between a gas leak location and the respective locations of the gas sensors based on the detected rates of change, and (b) calculates a location of the gas leak based on a triangulation of the first distance, the second distance, and the third distance.
