Project Introduction :
Code type prepaid intelligent gas meter is G series membrane type gas meter and flowmeter table as the foundation, equipped with code of intelligent control system, product implement GB/T 6968-1997 moshi gas meters B level technical standard, the skin membrane table: G1.6 ~ G100 series, flow 0.016 ~ 160 m3 / h; ROM. Watts flow meter: DG16 DG150 series, flow 0.9 ~ 250 m3 / h, the whole series adopt plain code input methods for table prepaid phone, without any carrier, the user need only will buy to eight of the manual input password intelligent table can realize the projects cost, also can through the phone and Internet to buy password, so that users for cost saving cost, and for the user save precious time.
Applied Range
Suitable for urban gas gas liquefied petroleum gas (LPG) and other noncorrosive gas measurement
Product Features
Automatic prepaid functions: first use after phone, inside the watch gas remaining original + new purchase = air ventilation
Data safe and reliable: table in a microprocessor, it may, according to user input different code to logic operations, if input code and operation of the match by code, then generation the meter will be the input code conversion to the corresponding measure, the same number of code every time table with the number of different buying and buying the different and change, different table of code number is not identical also, each table, when every purchase of different dosage will have one hundred million different sets of eight yards matching
Put an end to owe function: when purchases to cubic meters with, the controller to be automatic closing valves, users must timely purchases can use
Real-time computing functions: real time measurement and display value more than, buy in to zero tolerance to shut down air supply
Without electricity memory: built-in solid data storage, data permanent preservation
State display function: generation timers LCD display counter double, reading, intuitive, and light users according to inquires when key, display table, new purchase amount to buy the remaining inventory measure error code number times use accumulation memory closing valves reason of the state
Surplus prompt functions: when in table with more than the set to air (air cushion table 50 m3, mean table allowance 2 m3) alarm prompt
Automatic voltage alarm function: when the electrical down until a certain time will be owed pressure alarm, must change the battery within 72 hours, or automatically shut off air supply
The stolen can qigong: in a outside interference or illegal operation of automatic shutoff valve will air, wait for after normal can automatically move restore gas supply
Automatic BianWei function: when input the wrong data, the controller are not acceptable, and record the number of mistakes, such as eight times input errors, control system fully closed, only please operators might be able to unlock
Simple maintenance function: set up external battery warehouse, convenient to replace the battery
Anti-jamming performance is strong: adopt high quality double reed pipe alternate way of working, which can effectively prevent tremble, and the dose of the return water bring error, and can detect the interference of outside magnetic field, ensure mechanical parts and electronic parts counting consistent, if there is interference of outside magnetic field, two dry reed pipe is also suck and of controlling start close the valve program, can effectively prevent man-made strong magnetic and vibration interference
Automatic a sleep function: as a result of the static electricity technology work, 30 s no operation in will be in a suspended posture, ensure the battery for long-term use
Record fault information function: to all sorts of possible failure do the code set and do memory, even if off electricity to power lost memory before the failure causes of, for future check and repair, in time for the analysis judgment out fault provide convenient
Gas alarm function: if users to choose is with gas alarm gas meter, so when gas meter of gas equipment after a gas leak and reach the gas alarm when the density, connected to the generation of meter above the buzz a sound alarm, and alarm will sound an alarm signals will code gas meter valve closed in, cut off the air after gas meter, when a gas leak troubleshooting, user manual in digital form according to 01 * key, the valve will automatically open, code gas meter back to normal use
Close valve memory: in the user use generation in the process of meter, because users owe battery electric power generation now owe error input eight times or more gas alarm and man-made destruction and collation reason such as the structure, the meter will close valve generation, caused by the above problems closing valves and collation will do memory, so as to help us judge closing valves reason inquires the method of valves closed reason to see the use of the controller code manual closing valves reason inquires place we would greatly function after-sales service, can with the fastest speed and find out fault reason, protect a user use
Owe the prompt functions: and the external timers are ordinary alkaline batteries, normal new battery can be used both two years or so, when the battery power to the regulations voltage, the meter will owe electricity generation a close valve valve closed instruction, so as to prompt the user to replace the battery in close the valve and liquid crystal display will be owed to the bottom right corner of the symbol, right now allows the user to manually 01 * open valve according to continue to use, but must in 72 hours to replace batteries or valve will because owe electricity completely closed again, can not open only replace new battery (table > 0 in allowance) valve resume normal use
Close valve power function: because generation is external battery meter, so users can easily will battery warehouse out, play the role of the power, if so do, then the bottom right hand corner of the screen meter generation will be owed electricity symbols, according to the rules, the user to within 2 minutes will insert the battery storehouse, otherwise the generation of timers valve would automatically shut off, according to restore power until 01 * key valve opens normal use
