Industrial IC Card Intelligent Flow-meter

Description features:¡ñ Overview of Product Industrial IC Card Intelligent Flow-meter serial products cover various diameters from DN50 to DN300. They are mainly applicable for industry boiler users and some particular occasions. The series of product adopted advanced technologic solutions such as CPU card, ESAM safety module and matching intelligent controller to meet the requirement of industrial grade product design. They are adaptable to different kinds of installation & usage environment and their maximum working pressure is over 0.4MPa (4Kg). ¡ñ Main Technical Characteristics 1. Its subscription charge pre-collection and auto measurement functions have brought about the gas usage & control automation. 2. Advanced technologic solutions such as the industrial grade MCU, liquid crystal display device and integrated circuit have been adopted for the control section of the meter. The MCU can meet the design and utilization requirements due to its advantages of a higher reliability, having more I/O interfaces, and a larger memory capacity. 3. Advanced devices recommended by the State Ministry of Construction such as the CPU card & ESAM safety module have been adopted for its IC card to bring about the multi-layer secret code key management, which has, in turn, laid a good foundation for the security, confidentiality, reliability of the system data, and has made it feasible that the one card may function in a multi-functional and a multi-purpose manner. 4. Large screen liquid crystal display can display in Chinese language 6-digit gas flow digital information, including information ¡°valve closed¡±, ¡°In sufficient gas amount¡±, ¡°malfunction¡±, ¡°low power¡± and ¡°fake card¡±, etc. In addition, automatic calendar information such as ¡°year¡±, ¡°month¡± and ¡°day¡± can also be displayed. 5. A large capacity lithium battery design and a micro-power software & hardware design have been adopted to prolong the service life of its battery. 6. real time built-in clock chip designed in the system can record user accumulative gas consumption and the gas consumption per day & per month. The corresponding user¡¯s gas consumption data can be transmitted to the gas company for analysis and statistics purposes. 7. A battery power high-low status detection function has been designed within the control system for monitoring purpose. When the battery power is insufficient, the system alarms the user with the warning sign of ¡°low battery¡± and reminds the user to change battery. If the battery electricity is used up, the valve shall be automatically closed and the gas supply will be cut off. 8. The multi-fold safety protection function guarantees the safety & reliability of the system operation. ¢Ù Safety gas flow limiting function; ¢Ú Switch box protection function; ¢Û Disconnection protection function; ¢Ü Electro-magnetic interference protective function;
