1. Overview
Smart IC card domestic diaphragm gas meter CG-L-G4 is a smart gas volumetric meter, which realizes the function of prepayment and automatic calculating fee by using IC card. Gas provider can sell natural gas to customers in advance by using computer management system. By using computer management system, Gas provider can also set password to each IC card and save customers’ primary information, the serial number of gas meter, etc into the IC card and the computer management system. It is a wonderful measurement instrument for gas management.
2. Features
(1) Error of mechanical-electric conversion:
It is a high-tech product adopting reed switch count and built-in electrical motor control valve. Its min-measure unit is 0.01m3, which is the highest electrical measure class in domestic market. The cumulative error of mechanical-electric conversion is less than 0.01 m3
(2) Anti-theft and anti-teardown.
(3)LCD screen, voice and symbol warning.
(4)Antimagnetic, power-off data protection
(5) Low gas volume warning, low pressure warning, low-battery warning and power-off shut valve.
(6)When the flow-rate is over, the valve will shut off automatically.
(7)By connecting gas leaking annunciator makes it safe and reliable to shut off the valve. (Special option)
