Smart Gas Meter

Energy Meter
LoRaWAN Smart Gas Meter
A combination of base meter with built-in motor valve and smart controller with LoRaWAN communication module. It is the latest generation of LoRa wireless gas meter product that conforms to the LoRaWAN international standard. Based on high reliability network technology, prepaid module is strongly recommended for LoRaWAN gas meter which makes remote daily block pricing billing realizable, and to make sure the billing more reasonable and precise. The power consumption is lower based on the particular network communication, which makes the alkaline battery life time more than 1 year. . As the leading total solution provider in the gas industry, Goldcard provides the integrated solution for the utility. To satisfy varies requirement from different customers, Goldcard provides a solution from meter to system including LoRWAN gas meter, LoRWAN  data concentrator, data collection system, data marketing system and data cloud platform.
