Abstract

L'invention concerne un procédé de détection et/ou de quantification de fuites d'eau sur une canalisation d'eau ainsi qu'un dispositif pour la mise en oeuvre de ce procédé. Le procédé de l'invention consiste à mesurer le débit de l'eau s'écoulant dans la canalisation en au moins deux points distincts, l'un en aval, et l'autre en amont, du point de fuite supposée, la mesure du débit de l'eau étant effectuée en injectant de manière instantanée en un point en amont, et en un point en aval, du point de fuite supposée, un traceur modifiant la conductivité de l'eau, en mesurant la conductivité de l'eau en continu en aval de ces points et en calculant à partir des valeurs de conductivité les débits d'eau s'écoulant en amont, et en aval du point de fuite supposée dans la canalisation. Le procédé de l'invention trouve application dans le domaine de la quantification d'un débit de fuite même très faible.
