Major function:

1. Automatic control of gas filling process, with double-sided automatic display of gas filling volume, gas filling amount, and unit price (display with night light) during the filling process;
2. Three line pressure automatic switching ensures accurate and reasonable gas intake for the three bottle group;
3. Gas dispenser refueling pricing display: “refueling volume”, “unit price of one yuan/m3”, “amount of one yuan”, and equipped with a pressure gauge to display pressure;
4. It has power-off data protection and displays the current refueling data;
5. Large capacity storage, capable of querying refueling data for no less than 12000 times;
6. Monitoring system: Monitor the temperature, pressure, and flow rate during the inflation process, control the inflation speed, and automatically close the valve for protection when the pressure and flow exceed the standard;
7. Gas filling control system: Control the gas intake of the gas storage cylinder group to ensure a large inflation flow rate;
8. Built in imported clock system, accurate and reliable timing even after power failure;
9. Pressure protection function: When the refueling pressure exceeds the national regulated pressure value, the refueling will automatically stop;
10. The total accumulated amount can be queried at any time;
11. It has a preset refueling function with fixed gas volume and fixed amount;
12. Adjustable three line refueling pressure, flow rate, and gas density;
13. Configure the breaking valve (breaking force of the breaking valve: ≤) 400N), inlet ball valve;
14. Can check each refueling data and refueling time; Can query the cumulative gas volume, amount, total cumulative gas volume, and total cumulative amount of refueling during the shift;
15. It has automatic fault detection function and can automatically display fault codes;
16. During the inflation process, the pressure can be directly displayed and the inflation pressure can be adjusted to ensure rapid inflation;
17. The refueling hose has a pull-out protection function;
18. It has the functions of pressure relief and sewage discharge; Capable of online cleaning of filters without disassembling them;
19. Equipped with a manual emergency shut-off valve;
20. No traffic signal, automatic shutdown to protect the interests of homeowners;
21. It has RS485 communication and can communicate with the computer management system of the gas station;
22. It has the function of printing receipts;
