Atmos® - NFC/GPRS / NB-IoT Smart Diaphragm Gas Meter

The GPRS/NB IoT gas meter is a smart gas metering device based on our mechanical diaphragm gas meters. It is equipped with a built-in shut off valve basement and a smart controller with a GPRS/NB-loT communication module.

By connecting to the GPRS/NB-IoT wireless network, the following functions are available:
  • Metering data transmitted to a cloud platform for analysis
  • Block pricing
  • Various Alarms: low balance and low battery alarm, temper alarm, leakage alarm, overflow alarm.
  • Remote monitor, remote control
  • Remote valve control
  • Automatic shut-off valve
  • Combined with new media channels to achieve remote charging and real time interaction
Features
  • GPRS/ NB-IoT communication technology
  • Optical sampling
  • Fast shut-off valve
  • Lithium battery with more than 10 years for the service life.
