Introduction: Equipped with our companyí»s code controller, base meters are bought abroad to realize the prepaid and control functions, thus to achieve the automatic control of different functions of this new type of gas meter. Range of application: This product can be applied to the measurement of gas, natural gas, liquefied petroleum gas and other non-corrosive gases in the city. Main features: Automatic prepaid function: charging before using of it, water meter residual capacity= the original gas + newly purchased gas Auto-control function: switching the gas path automatically according to the payments and gas situation. Real time computation function: measuring on the real time and display the stock value, closing gas source automatically when the purchased gas is used up. Power-down memory function: solid state recorder is internally installed and the data will be permanently preserved. Status display function: displaying the amount of newly charged gas, the remaining stock and cumulative use, as well as low-voltage state etc. Prompting function: warning when the remaining gas is used to the set value or other functions are out of work. Overdrawing function: able to set a certain overdraft gas according to the user needs Automatic alarm function: when the voltage is lower than certain point, alarm system will be operated and the battery must be replaced within 72 hours, otherwise, it will automatically shut down the gas resources. Anti-gas-larceny function: shut down the gas supply automatically when there are theft of gas or illegal operations Technical parameter: 1ú¬base meter operation criteriaú¦gb/t6869 q/ofd.001-2007 jjg577-2005 2) current working voltageú¦3.00v 3ú¬cuiescent currentú¦=8 years 5ú¬life span of valveú¦switching frequency more than 5000 times 6ú¬accuracy degreeú¦level b 7ú¬four anti-functionú¦anti-attack, waterproof, anti-smoke, anti-knocking
