DEVICE FOR BIDIRECTIONAL REMOTE WATER-METER READING BY MEANS OF RADIO, FOR INVOICING IN ACCORDANCE WITH CONSUMPTION TIME BANDS

摘要

The present invention relates to a device for remote reading of water meters (8), comprising a set of acquisition (10) of consumption data and comprising at least one radio transmitter for transmitting the acquired information, at least one radio receiver. integrated into the acquisition assembly (10) so as to make said device (1) communicating in both directions to receive information from a central office (2) and an antenna (11) so that said central office can transmit information time stamping so that this transmission of information taken into account by said radio receivers makes it possible to guarantee an exact time stamping of all the acquisition assemblies (10) of the meters forming a same park, characterized in that said counter (8) starts a measurement of volume consumed at a time determined by a first time stamp received from the central office (2) by the receiver and stops it at a time determined by a second time stamp received from the ce ntral (2) by the receiver, the volume consumed in the interval between the two time stamps being stored in a memory and then transmitted to said central (2) via the transmitter at a deferred time.
