LoRaWAN Remote Transmission Wireless Gas Meter For Gas Resource Management

LoRaWAN Large Caliber Remote Transmission Wireless Gas Meter For Improved Gas Resource Management And Billing

• Product Overview

The large caliber wireless remote transmission gas meter is composed of a base meter, a main chip, a wireless transmission chip, a liquid crystal board, a motor valve, and a Farad capacitor. Combining the advantages of wireless remote transmission gas meters and prepaid IC card gas meters, it can realize the remote transmission function of gas meters. A new generation of intelligent meters with pre charging functions. The entire control system requires no wiring, stable communication, and accurate meter reading. The unit price of the gas meter can be adjusted through a meter reader to avoid economic losses caused by users hoarding gas after the gas price adjustment. The comprehensive performance meets the national standard GB/T6968. It is an ideal instrument in intelligent gas meters.
