Abstract

The current invention discloses a wireless monitoring system (8). The system (8) has one or more monitoring devices (14). Each device (14) can transmit data to and receive messages from an output center (18) or alarm system (19). The output center can also transmit and receive messages. Both the output center (18) and each device (14) preferably have a transceiver (43) that enables both the transmission (42) and receipt (44) of messages. No remote terminal units or hardwiring is required for the system to function. The system is truly a wireless gas monitoring system (8). The system (8) may use low earth orbit satellite (22) technology, or licensed radio frequencies or any other means to wirelessly transmit and receive messages.
