CG1.6LYC/CG2.5LYC wireless remote gas meter is a new type of intelligent gas meter composed of a membrane gas meter as the measuring base meter, and equipped with flow signal acquisition module, wireless RF transmission module, IC card module, valve control module, and power management module

The CG1.6LYC/CG2.5LYC wireless remote gas meter is a new type of intelligent gas meter composed of a membrane gas meter as the measuring base meter, a flow signal acquisition module, a wireless RF transmission module, an IC card module, a valve control module, and a power management module. This meter not only has the volume measurement function for gases such as coal gas, natural gas, and liquefied petroleum gas, but also has functions such as electromechanical conversion of measurement data, wireless data transmission, and valve remote control. The technical specifications comply with GB/T 6968-2011 and JJG 577-2012.
The gas meter complies with the standards of GB3836.1-2010 "Explosive Atmosphere Part 1: General Requirements for Equipment" and GB3836.4-2010 "Explosive Atmosphere Part 4: Equipment Protected by Intrinsic Safety Type" i ". The explosion-proof mark is Exib Ⅱ BT3 Gb, and it is suitable for Zone 1 and Zone 2 of II A-II B, T1-T3 explosive gas mixture locations. Passed the inspection by the National Explosion proof Testing Center and obtained the Explosion proof Certificate.

Scope of use: Suitable for measuring natural gas, liquefied petroleum gas, biogas, coal to gas and other gases.

Functional features:

1) Low static power consumption and long battery life;

2) Information such as insufficient remaining gas, low battery voltage, and valve status is displayed in Chinese, with an intuitive interface;

3) Multiple encryption verification for data access, secure and reliable;

4) Automatic detection and troubleshooting of sensor faults;

5) Abnormal information recording and gas meter usage data feedback function;

6) The maximum allowable gas storage capacity can be set to avoid users hoarding gas in large quantities and reduce losses caused by gas price fluctuations in the gas operating department;

7) Overdraft gas volume and alarm value can be set by users;

8) The maximum idle days of the gas meter can be set;

9) The face mask and module have undergone moisture-proof and oil fume proof treatment;

10) The management software adopts a modular design, with a user-friendly interface, intuitive and easy to understand operation.

11) It can achieve remote control of gas meters, including data reading, parameter adjustment, and switch control.

It is recommended to install in non combustible structures with good indoor ventilation.

It is strictly prohibited to install it in bedrooms, bathrooms, hazardous and flammable material storage areas, and places similar to the above situations.

The installation of gas meters should meet the requirements of meter reading, maintenance, upkeep, and safe use.
