1: The wireless gas meter with an independent work on normal days.
When the pipeline gas company need to meter reading every month, the wireless gas meters will send the specific wireless signal and form the wireless network. Every wireless gas meter not only send its own data, it may transmit the data as routing, and the measurement data will be pushed down to wireless data concentrator pass through 0 to multistage routing.
1: Intelligent wireless networking, which combining with direct transmission and mutitransmission in the routing way;
2: Which can autointelligence choice transmission path, configure itself and self repair and it is not easily disconnected;
3: Which can support fixed-timing meter-reading or Just-in-time meter-reading;
4: Which can change 48 channels freely with strong anti-interference ability;
5: The result of meter-reading with failure information will upload automatically;
