LoRaWAN large caliber wireless remote transmission gas meter for Improved Gas Resource Management and Billing
The large caliber wireless remote transmission gas meter is composed of a base meter, a main chip, a wireless transmission chip, a liquid crystal board, a motor valve, and a Farad capacitor. Combining the advantages of wireless remote transmission gas meters and prepaid IC card gas meters, it can realize the remote transmission function of gas meters. A new generation of intelligent meters with pre charging functions. The entire control system requires no wiring, stable communication, and accurate meter reading. The unit price of the gas meter can be adjusted through a meter reader to avoid economic losses caused by users hoarding gas after the gas price adjustment. The comprehensive performance meets the national standard GB/T6968. It is an ideal instrument in intelligent gas meters.
◆ It has the function of intelligently judging abnormal flow and automatically closing the valve;
◆ When the voltage is low or abnormal interference occurs, the LCD screen automatically displays fault information. Beep alarm prompt and close the valve;
◆ The user payment information can be saved in the form of pre deposit amount. The actual consumption amount of users can be deducted based on the gas price;
◆ Adopt FEC forward error correction technology to effectively increase the system's anti-interference ability. Improve the accuracy of received data;
◆ Adopt WOR radio wake-up technology. Improved meter reading response speed and reduced battery energy consumption;
◆ It can remotely monitor the user's gas consumption and battery usage, and remotely control the valve switch of the gas meter;
◆ It has a pulse signal open circuit self-test function. Effectively protect the accuracy of gas meter measurement;

• Price: The current gas price of the gas meter. And complete the gas meter measurement by deducting the amount;
• Remain/Dosage/Buy: The remaining gas volume of the gas meter, the cumulative usage of the gas meter, and the total purchase volume of the gas meter;
• Off/On: indication of valve switch status of gas meter
• Payment: When the remaining gas volume of the gas meter is less than the unit price, the prompt "Please pay" will be displayed. Please recharge in time to avoid closing;
• Lobat: when the battery voltage of the gas meter is insufficient, the LCD screen will prompt "Lobat" and close the valve. After replacing the battery, press the button to open the valve.
• Card read exception: card insertion operation error. Or it is not the user card of the gas meter, and the LCD screen prompts C-1. Please check whether the card operation is correct;
• Fault code:
E-1: Data has been read in E-2: Card inserted reversely or not in this table
E-3: Purchase exceeds the limit E-4: Customer code error
E-5: Gas meter receives a forced close command E-6: Strong magnetic interference
E-7: Wireless module fault E-8: Valve fault
E-10: Pulse signal input abnormality E-12: Leakage alarm
