product overview:

g1.6s-gi | g2 5s-g1| g4s-gi |wg2.5s-gi

gprs/nb iot/lora-wan/nfc gas meter is a smart gas metering product based on zenner mechanical diaphragm gas meter combined with a built-in shut-off valve basement and a smart controller with gprs/nb-iot communica-tion module.

with the connection of gprs/ nb-iot/lora-wan/nfc wireless network the following functions could be realized.

■data transmitted to cloud platform for analyzing

■block pricing

■alarm: low balance and low battery alarm temper alarm leakage alarmoverflow alarm etc.

■remote monitoring remote control

■remote valve control

■automatic shut-off valve

■combined with new media channels to achieve remote charging and real time interaction
