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.
