STAR IC Card prepayment gas meter adopts MSP430 series MPU control System, LCD and mechanical counter display with complete functions, reliable security. Main functions and features are as follows:
Special microprocessor IC and overall high reliability design. High capability of anti-jamming and assault proof.
 Ultra low energy consumption, stability, environmental changeability proof and long consecutive operation, prompt operational speed.
One card for one meter: user card can only be used on its own meter.
Data of user card adopts advanced encryption technology against forgery, coping, decoding and human attack, etc
Data of gas-purchase in user card is valid for only once and once it’s inserted into the meter, the data will be erased from card automatically.
The user can put into the user card or use the inquiry button to check the left gas volume and total gas consumption at any time.
 User card can be used repeatedly with a service life of around 100,000 times, easy to maintain with magnetic the card is against magnet and water and easy to keep.
Special structure design, convenient operation and maintenance.
Adopting double reed-switch to count the pulse. Accurate measurement, high sensitivity and proof from intentional destroy
 Mechanical and electronic integrated design, inside electromotor valve structure of accurate and secure operation
Has many individuation function setting (balance gas volumealarm threshold setting, valve close time setting)
 Alarming in the unusual conditions (when balance gas volume not enough, wrong operation, battery voltage tips, the valve fault tips)
Close the valve automatically in the unusual conditions ( when balance gas volume not enough, deficient pressure of battery, wrong operation, malice attack, long time no use)
Data storage function (wrong code, remain gas, accumulate gas, total purchase, purchase time, use number, alarming gas volume, etc), can read by the read card, and the information can store for more than ten years. Data storage functions (cumulative gas volume, users’ code, and other information) for more than 10 years.
CPU card available, can realize the “all in one card” function of water, energy and gas meter.
Product was supported by the gas sale terminal and gas sale information management System, in which can realize Systematic and network management.
It can realize Systematic Internet connection and also management according to sections or classes; thus can be against mutual disturbance and block human attack.
Take the computer as the management center, to achieve standardized administration of user’s account opening, gas purchasing, gas using and fee paying.
