This product contains the following details
CG1.6LYC, CG2.5LYC(Aluminium Case)Wireless remote transmission gas meters are type of new smart gas meter which is composed of flow signal acquisition module, wireless RF transmission module, IC card module, valve control module and power management module, with the diaphragm gas meter as a basic. The gas meter measures the flow rate of combustion gases like natural gas, liquefied petroleum gas (LPG), coal gas with the function of data conversion, wireless data transmission and valve control. The technical performance complies with GB/T 6968-2011 and JJG 577-2012.
The gas meters comply with GB3836.1-2010 Electrical apparatus for explosive gas atmospheres, Part 1: General requirements, and GB 3836.4-2010 Electrical apparatus for explosive gas atmospheres. Part 4: Intrinsic safety “i”. The gas meters’ ex-mark is ExibII BT3 Gb, and they are applicable to the place of II A-II B Zone 1 & Zone 2 and T1-T3 Explosive gas mixture. The gas meters are inspected and approved by Test Department：China National Quality Supervision and Test Centre for Explosion Protected Electrical Products (CQST) and obtained Ex Certificate of Conformity.
Function feature:
Lower static power consumption, and longer life-service of battery;
Visualized interface and Chinese display for the information like inadequate residual gas volume, battery under-voltage and valve status etc.;
Multi-encryption authentication for data save and access provides safety and reliability;
Automatic sensor fault inspection and handling;
Abnormal data recording and operating data feedback of gas meters;
Available to setup max. gas volume to prevent end user to accumulate large gas volume and reduce the loss at gas administration authority caused by gas price fluctuation;
Available to setup overdraft gas volume and alarm volume;
Available to setup max. days for non-operating status of gas meter;
Treatment of moisture proof and oil-smoke-proof has been adopted for cover and module of gas meter;
Adopt module design for management software with friendly human-machine interface, intuitive easy-to-understand operation;
Remote control. Data reading, parameter adjustment, switch control and other operations can be done remotely.
