Abstract
A method of detecting and locating a leak, the method comprising, for each ultrasonic fluid meter, the following steps of, acquiring or evaluating noise levels, each associated with a respective different detection period, each noise level being representative of the level of a leakage noise signal contained in the measurement samples coming from measurements taken by the transducer of said ultrasonic fluid meter during the associated detection period; comparing each noise level with a noise threshold; and detecting that a fluid leak is present in the proximity of the ultrasonic fluid meter on detecting at least a predetermined number of successive noise levels that are greater than the predetermined noise threshold and that correspond to detection periods that are spaced apart in time by at least a predetermined duration.
