NB-IoT smart gas meter
This is a smart diaphragm gas meter based on the mechanical diaphragm gas meter combined with a built-in shut-off valve and a smart controller with NB-IoT communication module.
The product is to realize the functions of ultra long distance, ultra-low power consumption, real-time online wireless remote control and remote meter reading by installing NB-IoT communication module and SIM card. It enables gas utilities to read a meter without entering the home. The gas utilities can manage the information of residential and meters through NB-IoT application system, to a great extend saving the cost of manual meter reading.
The product meets the requirements of the EN1359:2017, OIML R137:2012, IP65 degree & ATEX standards.
