Abstract
Localisation des fuites de réseaux de distribution d'eau. Pour évaluer les pertes d'eau (fuites) dans une canalisation 1 associée à une conduite 23, on isole une partie du secteur par fermeture des vannes telles que 2, 21, 22, 15. Puis au moyen d'un camion 16 on rebranche l'entrée et la sortie du secteur isolé en mesurant les deux écoulements correspondants. La différence qui subsiste lors de la période de consommation minimale correspond à la perte. On peut faire varier la pression, relever les bruits de fuite, etc. Application à tous les types de réseaux de distribution.
