DEVICE FOR DETECTING WATER LEAKS IN PIPELINES AND LEAK DETECTION METHOD.

摘要

The invention relates to a device in the form of a small sphere that has neutral buoyancy, inside which at least one hydrophone (2) is provided and connected to a signal processor (9) which stores information in a memory card (10) and is powered by at least one battery (11). The signal processor (9) comprises a clock module (12), allowing the elapsed travel time to be associated in the memory (10) with each audio signal received by the hydrophone (2), such that, based on the travel time, it is possible to establish the exact position of anomalies or detected leaks. The device further comprises a series of regularly spaced external synchronisers which are used to offset the position error that can accumulate in the device. The resulting device is simple, cheap, solid, durable and extremely effective.
