Features 1. The gas meter applies to natural gas liquid petroleum gas and other high caloric gases. 2. The gas meter bears the characteristics of excellent flux curve, stable performance and accurate metering. 3. The battery External installed for convenient maintenance. 4. PCB well covered for waterproof,suitable to be used in humidity environment. 5. Adopting large-capacity chip, reducing external circuit, high reliability and rare failure . 6. Dual display, both in mechnical and LCD, more reliability. Smart functions 1. Auto-control: Valve closes when remaining balance is 0,and opens when inputting value. 2. It can generate corresponding code automatically for gas meter and IC card to ensure its safety and reliability. 3. Anti-magnetic interfered: The valve closes automatically,when interfered by magnet, and valve opens by swieping IC card if interference eliminated. 4. Alarm prompt: The valve closes to remind user to buy gas,when remaining balance reaches alarm limit (2m3) (set according to user's request), and valve opens by swieping card on this situation. 5. Power Warning: Power is insufficient, LCD displays the symbol to remind user to replace batteries 6. Valve closes if not replacing the battery in time after above reminding. 7. LCD : LCD displays total used amount, remaining balance, valve and power status, fault codes and other information. 8. Checking: LCD no display normally, check readings by swieping IC card on meter. 9. Data feedback: Data in meter can feedback to managing system by card, convenient for management. 10. Management Cards: Checking card, transfer card are used for maintain operators. 11. Onecard for multy meters: One card can manage eight kinds of meters, such as water meter, watthour meter, gas meter, heat meter, etc.
