Dual mode intelligent household membrane gas meter


The R108 series dual-mode intelligent household membrane gas meter is an intelligent gas meter that combines the advantages of traditional IC card meters with emerging wireless reading advantages. It is easy to install, does not require wiring, and is easy to operate. By adopting bidirectional wireless communication and unique network relay meter reading technology, the perfect combination of early gas recovery fees and outdoor (remote) reading and control needs of operators is achieved, making it a good choice for high-rise residential gas metering products!

function and characteristic


  • Prepaid gas fees and gas volume control function;
  • Bidirectional wireless communication, network relay meter reading patented technology (15 level relay, capable of reaching 50 story high-rise buildings);
  • Multi layer data encryption and verification, accurate data collection without garbled characters;
  • Multiple billing methods for gas volume and amount; Support tiered gas pricing and real-time price adjustment function;
  • Ordinary alkaline batteries and lithium batteries are optional;
  • Outdoor or remote reading of operational data (total usage, pre stored gas volume, battery level, valve status, etc.) and valve control function.
