OVERVIEW：
Ultrasonic gas meter is a new fully electronic meter that uses ultrasonic principles for measurement. It has the advantages of high precision, wide range ratio, high stability, and maintenance-free.
4G/NB-IoT Ultrasonic gas meter is used for measuring the gas flow in the pipe, with functions of remote prepayment, data uploading at fixed time, wireless network remote meter reading and remote valve control. In addition, it is compatible with local infrared communication, with simple operation, strong anti-interference ability, and low power consumption, making it especially applicable to civilian wireless remote gas metering system.
The gas company collects gas fees and input the purchased amount into the gas meter via 4G/NB-IoT network. When in use, the gas meter will automatically deduct the amount based on the set multi-tariff gas price. When purchased gas is used up, the gas meter will close the valve to stop gas supply. The user has to purchase gas again for continual use.
FUNCTIONS:
1) Adopt industrial level NB-IoT module, SIM card adopts industrial M2M IoT SIM card.
2) Adopt dry/lithium battery, and battery service life is more than 8 years, and if the power is failure, the data can be saved for 30 years.
3) Remotely prepaid function, support 5 tariffs 6 prices to be set, bill calculation mode can be set as monthly, quarterly or yearly.
4) Timing period data upload, uploading interval can be set, and uploading data includes: the daily gas consumption of current month and last month, accumulated gas consumption, balance (gas quantity), and etc.
5) Two online intervals can be set , and real time meter reading can be realized during the online interval.
6) Alarm when being attacked, low battery power, low balance, valve failure and owing.
7) LCD display, it can display gas consumption, signal strength, battery level, valve status, and etc.
DIMENSION：
MAIN TECHNIQUES:
1) NB-IoT technology: transmits data via public network.
2) Micropower consumption technology: adopt timed test technology; static current is less than 20μA.
3) Motor valve technology: adopt modern motor valve; work reliably with low pressure loss.
4) Totally sealed design: all the circuits are sealed by high performance casting glue with good tightness and no exposed electrode.
5) Freely set online period: Remote meter reading during online period.
