This series of wireless remote transmission IC card membrane gas meter is a new generation of intelligent gas flow meter which uses IC card to realize pre charge, automatic measurement of gas meter, wireless remote monitoring and other functions. It can be widely used in natural gas, gas, liquefied petroleum gas and other combustible gas. It is an innovative intelligent gas meter that combines wireless remote gas meter and IC card gas meter perfectly. Wireless remote transmission IC card membrane gas meter uses microcomputer and special control program to realize automatic data processing. The gas management department can pre sell the gas volume to the users through the computer gas sales management system, set the password for the IC card, and can store the user's factory table number, wireless communication address, wireless communication parameters, meter constant, initial value of mechanical measurement, user address, name and other initial file information records as required.

   Technical Parameter

Characteristic

· According to the needs of gas companies, prepayment and post payment mode can be selected.

· As a prepaid storage medium, IC card has the advantages of no fear of magnetic field, scratch, forgery, strong confidentiality, large storage capacity and high reliability.

· It has the functions of anti gas theft and anti disassembly, and can be equipped with one-way door.

· It has the function of liquid crystal display gas amount data and Chinese character prompt status information, which is intuitive and convenient for user

· The user password, wireless communication address and other parameters can be set. The table is one-to-one corresponding to IC card and wireless communication address. It can not exchange IC card and modify wireless communication address and other parameters privately, that is, one card, one table and one communication address.

· The double stem reed technology and Japanese Oki products are adopted to ensure the accuracy of measurement more reliably.

· The latest Lora spread spectrum communication technology is adopted to maximize the effective meter reading distance, and the meter routing function can be opened.

· Special frequency band: 495mhz center frequency is adopted to avoid 471-486mhz frequency band of power system to avoid mutual interference

· It is equipped with a dual power supply system with high capacity built-in battery and external battery. When the user does not install the external battery or the external battery has low power, the valve will be closed, but normal meter reading can still be carried out.

· It is equipped with gas sales management system, wireless meter reading system, wireless meter reading collector and intelligent meter reading terminal, which can realize remote control functions such as non household meter reading, real-time change of unit price, remote control of valve switch and other remote control functions, real-time monitoring and statistics of the user's use status, further realizing the automation and modernization of gas sales management.
