operating principle
When the flow of gas through a gas meter, because the mechanism of the friction and block, can produce the pressure difference in the gas meter import and export, the main push diaphragm gas meter diaphragm pressure difference in measurement indoor sports,promoting the coordination of valve-train distribution at the same time, make for continuous reciprocating movement of the diaphragm, diaphragm gas meter through the crank rocker mechanism, transform the linear reciprocating motion into circular motion,circular motion and then by institutions promote counter rotating movement transmission, record the number of diaphragm reciprocating motion, because every reciprocating diaphragm, discharge amount of gas, counter by the transformation of the transmission chain, eventually the volume of measured gas is displayed to achieve the purpose of measuring gas.
Main fratures
1)Office meter reading:It uses smart control module, meter reading personnel do not need to go to the door to read the meter,just log on to the gas management website on the computer, choose the community or users who need to read the meter, you can achieve group copy copy, achieve the office read the meter, reduce the work intensity of meter reading personnel, improve work efficiency.
2)Fee payment:Users do not need to go to the business hall of the gas company to pay fees. Users can choose the online recharge platform, APP or third-party platform of the gas company to pay fees.(Need to consult gas company, whether to support the above recharge way)
3)Low power consumption and easy to replace, the battery can last more than 12 months.
4)voltage detection:When the battery undervoltage is detected, the indicator light of the meter will turn red, and the user shall replace the new battery as soon as possible (no. 5 alkaline dry battery, 4). When the battery is exhausted, the indicator light will go off, and the meter valve will automatically close, and the user shall replace the new battery (no. 5 alkaline dry battery,
4).If the lithium battery is used, please contact the gas company when the battery needs to be replaced, and the professional personnel shall replace the battery.
5)Good protective:The controller shell adopts special dustproof and waterproof design with protection grade IP65.
Product operating environment
1.temperature:-10ºC~40ºC;
2.working pressure:0.5kPa~30kPa;
