Code Type Prepaid Intelligent Flow Meter

Applied Range

This flow meter for city gas gas liquefied petroleum gas (LPG) and all the other gas measurement.

Product Features

Automatic prepaid function: the first to buy gas used in the table more than the original gas gas = new purchase + maintained.

Surplus prompt functions: when in table with more than the set to air (atmospheric table cushion = 50 m) off the tip.

The automatic control function: according to the situation and fuel gas fee automatic control gas lead to break.

The stolen can qigong: generation used electronic sign occasionally seal etc protection measures, in be outside interference or the illegal operation, the valve will automatically shut off, stay to move back to normal after use.

Real-time computing functions: real-time calculation and display value more than enough to chill with to zero is to shut down the air valve.

Automatic distinguish the true from the false 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..

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 more different, each table, when every purchase of different dosage will have one hundred million different sets of eight yards matching.

Simple maintenance function: generation timers set up external battery warehouse and panel shows fault message, and other functions, for in the future maintenance to provide more personalized service.

Display features: generation timers LCD display counter double, reading, intuitive, and light users according to the key inquires, can appear on the surface residual quantity use accumulation, buy the password table measure error code number of times, the error code reason of the display.

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.

Long service life: generation for low power consumption meter, overload ability, static working current circuit is nearly zero mA, count signal control electricity, finish work without power and press the start button electricity, enter the code 30 seconds don't button will automatically without electricity, and, in the battery (electric meter without battery) most of the time dormant.

The battery external function: to greatly convenience of customers, we will occasionally, the power supply power generation set to the outside, USES ordinary alkaline batteries, contemporary timers battery without electricity, users can put out battery storehouse, the replacement of the new common battery can restore power.

Power lost protection function: to all sorts of possible failure do the code set and do memory, even if power lost to memory the cause of the problem, for future check and repair, in time for the analysis judgment out fault provide convenient.

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), press 01 * key open the 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.
