Project Introduction
Code type prepaid water meter realized with cold water quantity and the water pipe flows through the calculation of water management control, has already won <<The People's Republic of licence for manufacturing measuring instruments>> and <<Measuring instruments type approval certificate>>, and the measurement level: B level, series model: DN15 ~
150.
Applied Range
Apply to urban water supply town industry and commerce base water supply.
Product Features
Operating extremely handy: generation by code system and occasionally issued with the keyboard watch body composition, the distribution system will users buy data encryption generation 8 digits code, users will import table in this code generation purchase quantity body declassified, because this kind of table countless according to the carrier, users could not only in the issue to buy your own code department, still can be in the home through the telephone voice and Internet buy code.
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.
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-interference function: because the body the fully closed and soft hardware program design of the dry processing, can effectively prevent man-made strong electrostatic and water infiltration.
Prevent stolen water function: 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 normal after can automatically move restored water supplies.
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.
Surplus prompt functions: the busy work life can be the user is easy to forget the monthly usage, so we set for the user in table is used when certain value surplus instructions to closing valves once, to remind consumer surplus will be insufficient, to prepare to buy dosage, then the user can also manually open valve continue to use the rest of the surplus when the rest of the surplus again used to value of 0 m3, the valve will shut down automatically, at this time the user must buy amount in table filled with only can open valve 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 automatically open back to 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, to restore power valve until will automatically be open back to normal use.
Close valve memory: in the user use generation timers process, because users owe battery electric power generation now owe more than 8 times error input and man-made destruction and collation reason such as the structure, and the meter will shut automatically valve, caused by the above problems to the closing valves and collation through the memory 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 to use.
