Domestic gas meter /steel shell membrane gas meter

The shell of the steel shell gas meter is made of high quality cold-rolled steel sheet, which is fully stretched and formed, safe and reliable；It is treated by surface outdoor powder spray, corrosion resistance；And it is made of phenolic resin with unique formula of valve cover seat and has good stability；It has high measurement accuracy;Low initial flow;Strong durability;High tolerance to gas medium;Easy maintenance；It is also equipped with engineering plastic base to avoid direct contact between the gas meter and the ground.

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.

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.

1.Before installation, the gas meter should be inspected first for appearance and then for sealing performance, so as to prevent installation and use of the gas meter that may cause damage during transportation.
2.When installing the gas meter, it should be noted that the distance between the center of the pipeline connected with the gas meter should be consistent with the distance between the center of the gas meter. It should not be forced to connect and twist to avoid leakage at the connection of the gas meter.
3.The gas meter should have sufficient safe distance from the stove and other fire sources.
4.Keep in mind：The air in the pipeline and gas meter should be emptied before ignition.Gas mixed with air can easily explode when it meets spark.
5.During transportation, storage and installation of gas meters, care should be taken to prevent falling upside down and water entering.
6.The fuel gas used should meet the requirements of the national standards and should not contain moisture. The condensed water in fuel gas will freeze the table and cannot operate normally
7.In order to avoid condensate water into the gas meter, the gas meter should be installed horizontally at the high point of the pipeline when installation should pay attention to the top of the case arrow, indicating the direction of gas flow, should not be connected to the reverse (because the table has anti-retrograde device).
8.The gas meter should be installed in a dry and ventilated place. It is strictly prohibited to install the gas meter in the
bedroom and bathroom, and should not be installed in the place where the gas meter is seriously corroded.
9.When the pipeline system leaks, it is forbidden to leak the open fire. When the pilot fire is carried out, the air in the gas
meter must be discharged to prevent accidents
10.In case of malfunction, please do not disassemble by yourself, please ask the technical personnel of gas company for
maintenance.
11.In case of gas leakage, first close the front table valve, immediately open doors and Windows ventilation.
12.Do not use open fire leak detection, carefully with soap and water leak detection.
13.This meter can not be used in the use of strong caustic soda gasoline alcohol solvent cleaning.
