Method for remotely reading fluid meters, and meter and server associated with said method
Abstract:
The invention relates to a method for remotely reading fluid meters, according to which a meter comprises a module having a metering clock and a wireless transmitter for transmitting a frame of time-stamped remote-reading information to a server which comprises a server clock; after every N frames are transmitted, the meter module enters a receiving mode (Rx) for a period of time (ΔRx); upon receiving a frame of time-stamped information, the server determines the difference between the time information contained in the received frame and the time information provided by the server clock; then, if the difference is greater than a predetermined limit (ΔL), the server sends a reset message to the meter; upon receiving the reset message, the module of the meter updates the meter clock.
