ABSTRACT:
A utility metering system includes a plurality of distributed utility meter readers. Each reader is associated with a respective electronic utility meter at a respective utility user station. Each meter reader comprises a transceiver for transmitting metered data received from the respective meter to a remote station via a GSM cellular infrastructure in the form of an SMS message. The data received is stored in a database in relation to a unique identification code number. In the case of meters for pre-paid utilities, the system enables users to obtain credit readings from the station from positions remote from the meters and also to replenish credits on the meters from such positions, by causing the station to transmit credit data prepaid for via the infrastructure to the meters.
