Performance characteristics
1. This product is suitable for natural gas, liquefied petroleum gas and other high-heat gas.
2. The product has good flow curve, high sensitivity, stable repeatability test performance and accurate measurement.
3. Batteries are external, and general alkaline batteries No. 5 are used to facilitate user replacement.
4. Fully sealed, multi-moisture-proof treatment, fully sealed circuit part, suitable for stable work in humid environment.
5. Using large-capacity chips to reduce peripheral circuits has high reliability and low failure rate.
6. Double display, double display of wheel and LCD, higher reliability and safety.
Intelligent Function
1. Auto-switch: charging, opening and using gas, valving without value, automatically switching on and off valves; pre-charging, no need to enter the home meter reading, charging.
2. Encryption security: One table (one household) and one card automatically generate and identify IC card passwords, which correspond to each other and are not interchangeable.
3. Anti-magnetic interference: When magnetic interference occurs, the valve closes automatically and opens automatically after swiping the card.
4. Early warning: When the residual gas is 2 m3 (set according to user's requirements), the valve is promptly closed, reminding users to buy water as soon as possible; at this time, the card can be switched on and the valve can continue to use gas.
5. Low-power warning: when the power is insufficient, the LCD display is insufficient, prompting the timely replacement of batteries.
6. Low-power shutoff valve: After several days of low-power warning, the valve closes and the battery must be replaced before the valve can be opened for gas supply.
7. LCD display: LCD display accumulative amount of water, residual water, valve switch, power status, fault code and other information.
8. Query display: the display is usually closed, and the user card is used to display the residual gas and cumulative consumption.
9. Data Writing Back: User Card can write back the data of water meter, read the working state of gas meter in management system, including faults, etc.
10. Management card function: inquiry card and transfer card are used by managers in inquiry and maintenance.
11. One-card design: It can realize one-card management of water meter, electricity meter, gas meter, heat meter and other measuring instruments
