■ Display: Uses LCD so that the user may, at any time, learn the total gas consumption, remained volume.
■ Warning: When remaining gas quantity is below the critical value, the system hints an alarm mark.
■ Shut-off: When remaining gas quantity is zero, the valve will shut off automatically.
■ Data setting: By using system software, alarm quantity over-consumption and upper limits can be set up flexibly.
■ Section billing: The monthly cost of gas consumed can be calculated separately as per the �ration price� and �negotiated price�.
■ Data transmission: Through IC card, two-way transmission of data can be achieved and data will be managed. The user data will be transferred to the computer system. The computer system will in turn pass the gas purchase data to the IC card gas meter.
■ Provision for Automatic warning of gas leaking.
■ Magnetic interference-proof: When the gas meter during operation encounters strong external magnetic interference, the valve will shut off automatically. When interference disappears, the valve will open again automatically.
■ Data protection: Using 3.0V lithium battery when the voltage is lower than 2.1V, displaying battery voltage lower sign, after 72 hours the valve will automatically shut off and the built-in data can be stored for ten years.
■ Sparing malicious damage: The structure of IC card gas meter is designed to spare malicious damage. The electric circuit of the meter can resist invasion of heavy current and short circuit, it records information about any intended damage.
■ One or several cards are used for one meter. The gas sales management unit may do the card setting as per requirements. In case the card is damaged or lost, the user may obtain a new card according to record on the sales management system.
■ Stable performance and wide application, as it uses the low consumption integrated chip, automatic sleep technique, the service life of lithium batter will be more than 5 years, smaller 8 years.
■ Good anti-magnetic and shower-poof performance.
■ Synchronous displaying of mechanical and electronic metering data is provided.
