YQ-W-G1.6, 2.5, 4, radio remote reading diaphragm gas meter is actuated by its microcomputer and special control procedures. With the help of the microcomputer gas service center can preset client’ s address and code, collect the client’ s gas consumption data in a remote way, exercise effective monitoring and control of the whole gas sales and consumption process. It is an efficient means to promote intellectual and informational administration of the gas service center.
Special Features:
1. The gas meter has anti-theft and illegal access resistance function;
2. The client’ s secret code and communication information can be preset in the microcomputer. Once the client’ s data has been set in a gas meter, the communication address cannot be changed.
3. It adopts advanced double sensors technique, which ensures its accurate measurement;
4. The meter is installed with necessary soft ware, which can exercise effective monitoring and control of the whole gas sales and consumption process.
5. The meter is equipped with lithium battery for its power supply, which can provide to the clients sufficient power for long period of time.
6. When there is magnetic interference, the valve will shut off automatically and alarm light will turn on.
7. When the lithium battery is power off or in low voltage, a light in LED display will turn on to remind replacement of new battery.
