Cet inconvenient est un obstacle majeur lors du releve des compteurs, parce qu'il n'est pas toujours possible d'acceder au seul dispositif de transmission implante en un lieu unique. This disadvantage is a major obstacle in the notes counters, because it is not always possible to enter the single transmission device implanted in one place. Ce lieu peut etre en effet rendu inaccessible pour differentes raisons et il n'est pas possible de demultiplier le nombre de dispositifs de transmission This place can indeed be made inaccessible for various reasons and it is not possible to multiply the number of transmission devices
