LoRaWAN Smart Gas Meter Secure Gas Consumption Meter Lithium
Battery Digital Meter Electricity Bill
Intelligent gas meter is a new generation of centralized reading
gas meter terminal. It is applicable to the flow measurement of
natural gas, liquefied petroleum gas, artificial gas and other
gasuujes. It integrates gas meter metering, remote reading and
monitoring. The meter has the characteristics of high reliability,
high accuracy and low power consumption.
1. Adopt LoRaWAN wireless technology. Effectively increase the
anti-interference ability of the communication system and improve
the
accuracy of the received data.
2. The gas meter adopts the form of system prepayment. The valve
switch of the gas meter is realized by the command from the system
platform.
3. Timing (once a day)(settable) and key wake-up to transfer data
to the platform. It improves the response speed of meter reading
and
reduces battery energy consumption.
4. When the voltage is low or abnormal,the LCD screen will
automatically display the fault information, beep the alarm, and
close the valve.
5. It has a built-in antenna.The transmission signal is stable and
reliable.
6. The platform can remotely check the user's gas
consumption,battery usage,and remotely control the valve switch of
the gas meter.
