Wireless collection intelligent household membrane gas meter
The R108 series wireless integrated reading intelligent household membrane gas meter is automatically processed by a computer and a dedicated control program for data processing. Using short-range bidirectional wireless communication, gas meter operation data and status can be read or remotely transmitted without wiring. Solved the problems of difficult household registration, meter reading, and billing for gas companies. This product adopts patented technology of network relay meter reading to achieve relay of 15 levels or above, and can reach 50 story high-rise buildings, breaking through the bottleneck of short wireless transmission distance and greatly improving the accuracy and efficiency of meter reading.
