  CG-Z-JRB2.5 IC card household diaphragm gas meter can reach the  GB/T6968-1997 China national quality standards and Ministry of Construction CJ/T112-2000 industry-standard requirements, and adopts domestic gas meter JJG577-2005 test protocols, which is suitable for the automatic metering and charging of city gas pipeline, natural gas, liquefied petroleum gas, methane gas and other gas. The gas meter has two sets of display system: wheeled mechanical word display and LCD with microprocessor controller. Main technical parameters and characteristics: 1. JRB1.6, JRB2.5-type gas meter, the largest flow meter is 2.5m3 / h, the maximum working pressure is 10kPa. 2. The medium: Natural gas quality indicators should be consistent with the requirements of SY7514-88, gas quality indicators should be consistent with the requirements of GB13612-92. 3. Aluminum alloy die-casting shell, small size, light weight, corrosion resistance, easy installation. 4. Achieve " payment first, then consume" 5. Circuit board adopts the moistureproof technology , which can reach the national defence level. It can work in harsh environment. 6. Life service is up to more than 10 years , valve can be close tightly after the power is off. 7. With two display ways: mechanical display and electronic display, to ensure the measurement accuracy of gas meter. 8. LCD can display the available gas volume, accumulated gas volume, valve status, battery status and other parameters. 9. Resist illegal operation.
