meter. Under the condition with full signal coverage and without
any interference, the reading success rate can be up to 100%.
 Completely remote reading without any visit; automatic
reading with bidirectional data transmission on the monitored
meters can be done in the monitoring center or district
compute, and also the running status of the terminal meter
can be monitored at any time. The valve switch of the terminal
meter can be controlled remotely and the fault status, dosage
status, etc ., can be monitored at any time. The terminal can
also automatically report the fault information.
 Combination management; the terminal meter, wireless
repeaters, concentrator can be managed through software
and the topology construct of the reading system can be
adjusted;
 The statistics and query on the information such as statistical
query, business reports, on-demand user files, monitoring
records, business operations records and other aspects of
information, can be output as business form.
 Remoting recharge, which can support to recharge through the
ways both wireless and IC card;
 Remoting price adjustment; the gas unit price can be remotely
adjusted, in order to reduce the economic losses caused by the
fluctuations in gas prices;
 Real-time meter reading; the real-time gas information can be
read, which is easy to statics the production and sales status of
gas, in order to effectively control the different between
production and sale;
 Supporting multi-level routing, which can be suitable for signal
transit and transmission under various environments;
 Supporting compatibility with wireless handheld meter
reading device, which can be seamless integration or mutual
replacement, parallel use;
 Adopting patented wireless remote technology, which is
specially designed for monitoring and managing the domestic
meter, and also meet the low power consumption
requirements of terminal meter;
 Using wireless free frequency communication, which can be
combined with public GPRS network, without applying
frequency and easy to use;
 Easy installation and implementation, which only need to
provide the main regulator interface, and can be used
immediately without any more wiring and additional
configuration.
