GW series wireless remote smart gas meter is high-tech machronics product. This series meter uses advanced wireless transmission technology. Through microelectronic control circuits, it converts the pulse signals of traditional mechanical meter into electrical signals. Then the metering data is transmitted to background platform through GPRS network automatically, or it can be collected by a hand-held wireless unit from outside of the houses and after that downloaded to a computer through USB port.
