Claim:
1. A fluid leak detection apparatus comprising: a plurality of sensing devices, each sensing device comprising: an acoustic sensor, wherein the acoustic sensor is capable of detecting acoustic signals from a pipe used to transport a fluid; a battery electrically connected to the acoustic sensor, the battery having a capacity less than 1000 mAh; a housing containing the acoustic sensor and the battery; and a non-invasive coupling element configured to couple the housing to a location on the pipe; and a processing component in communication with the plurality of sensing devices, the processing component being capable of performing analysis on data captured from the plurality of sensing devices, wherein a system leak detection sensitivity of the analysis by the processing component is higher than a leak detection sensitivity of the sensing devices; wherein the processing component is configured to a) identify, from one sensor in the plurality of sensors, an acoustic frequency range that is active during a fluid flow event, and b) adjust other sensors in the plurality of sensors to focus on a subset of acoustic frequencies.
