СГБМ с радиоканалом LoRaWAN™ ВЕГА
Radio channel operation
The basis of the LPWAN technology data transfer principle (based on the LORAVAN protocol) at the physical level is the property of radio systems — an increase in the communication range with a decrease in the transmission speed.
The LoRaWAN network uses a star topology, where each device communicates with the base station directly. City or regional networks are built using the «star of stars» configuration.
A device with a LoRaWAN module transmits data over the air to a base station. The station receives signals from all devices within its range, digitizes and transmits to a remote server using an available communication channel (for example, Ethernet).
The data obtained on the server is used to display, analyze, build reports and make decisions. Device management takes place using a reverse link.
For data transmission over the radio channel, an unlicensed frequency spectrum is used that is allowed for free use in the network region (for example, 864-865 MHz).
CONVENIENT INSTALLATION AND MOUNTING
Coupling nuts enable to perform installation without the use of any additional connecting elements and a gas pipe tee in the gas meter kit makes it possible to pressurize gas pipes without the meter and enables you to use gas, if the meter is repaired or calibrated.
The electronic unit has Calendar function, which enables you to know, whether power was turned off during operation. All information is kept in the archive of the electronic unit, which can be read only with the use of special equipment.
REMOTE METER READING
Wireless data transfer using LPWAN technology based on LoRaWAN protocol.
Ability to work in any LoRaWAN networks.
In the version with LoRaWANTM VEGA gas meter SGBM is equipped with a radio module with wireless transmission of LPWAN data based on the LoRaWAN Protocol developed by Vega Absolut, with the ability to work in all LoRaWAN- networks.
SGBM gas meter with thermal correction brings measured gas volume in balance with temperature 20 °C. It enables a consumer to pay only for factual consumed gas regardless of seasonal gas temperature.
