Abstract
The present invention relates to a remote water-meter reading device (8) that comprises an assembly (10) for acquiring consumption data and comprising at least one radio transmitter for transmitting the information acquired, at least one radio receiver incorporated into the acquisition assembly (10) so as to enable said device (1) to communicate in both directions in order to receive the information from a central unit (2), and an antenna (11) so that said central unit can transmit time/date information such that this transmission of information taken into account by said radio receivers makes it possible to guarantee exact timing/dating of all the acquisition assemblies (10) of the meters that form one and the same lot, characterized in that said meter (8) initiates a volume-consumed measurement at a time determined by a first timing/dating received from the central unit (2) by the receiver and stops it at a time determined by a second timing/dating received from the central unit (2) by the receiver, the volume consumed in the interval between the two timings/datings being stored in a memory and then transmitted to said central unit (2) via the transmitter at a later time.
