G1.6 / G2.5 / G4 Wireless Smart Meters , LoRaWAN Smart Gas Meter With Module
Introduction:
The wireless transcription intelligent gas meter is high-tech
integrative 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.
This product is applied to metering of gas volume flowing across
gas pipe, and meter reading from outdoor or through remote
transcription.
Product Features:
Remote valve-control to solve arrearage problem.
Ladder-type pricing.
Three-level automatic routing to increase transmission distance.
ERFCU design, ultra-low power consumption.
WOR remote awaking technology to reduce power consumption.
Wamr Net routing protocol to ensure data security.
High speed transmission, data reading for single meter within 1.5
seconds.
Simple and practical structure with renewable battery.
Disassembly structure for electronic part, convenient for
maintenance.
Mainly applicable to new construction projects, or reconstruction
projects for old residential area which are inconvenient for wiring
deployment.
Wireless transmission technology is applied to realize out-door
meter reading, which simplified system installation by avoiding
wiring deployment.
The wireless transmission distance for hand-held unit is over 200
meters in open field.
Friendly user interface for management software of background
platform. Variety of formats for data output and customized link
with billing system according to customers'needs.

Structure and Working Theory:
Inside the counter of gas meter (mechanical part), there is one
magnet embedded under the wheel pointer for 0.01 m3 of gas and two
reed switches beside each side of the wheel. Each time the pointer
goes a circle, one group of two pulses is generated to represent
0.01 m3 of gas being calculated. The pulses are converted to
digital signals and recorded as metering data based on pre-set
program. Then the metering data can be transmitted to a
concentrator or hand-held unit.
Key Benefits:
LoRaWAN/PLC/RF/GPRS communication(On request)
Time of Use(TOU), muti-tariff, holiday setting.
Easy connection to User Interface Unit(UIU) for split type applications
15 year designed life
Balance alarm can be set by user according to his own need.
