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 remote water-meter reading device (8) thatcomprises an assembly (10) for acquiring consumption data and comprising atleast one radio transmitter for transmitting the information acquired, at leastone radio receiver incorporated into the acquisition assembly (10) so as to enablesaid device (1) to communicate in both directions in order to receive the informationfrom a central unit (2), and an antenna (11) so that said central unit can transmittime/date information such that this transmission of information taken intoaccount by said radio receivers makes it possible to guarantee exact timing/datingof all the acquisition assemblies (10) of the meters that form one and the samelot, characterized in that said meter (8) initiates a volume-consumed measurementat 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 receivedfrom the central unit (2) by the receiver, the volume consumed in the intervalbetween the two timings/datings being stored in a memory and then transmittedto said central unit (2) via the transmitter at a later time.
