At present, domestic smart gas meters mainly include IC card smart gas meters, CPU card smart gas meters, radio frequency card smart gas meter, direct -reading remote gas meter (wired remote watch), and wireless remote gas meter (accumulated) and so onThese major categories, with the improvement of peoples living standards and quality of life, the needs of intelligent product needs required by modern families will promote the development of intelligent gas watches in the direction of safety, reliability, and intelligent and convenient.
Smart gas meter failure
(1) Interference problem: The anti -interference ability of IC card gas meter is weak, especially in places with harsh environment, such as the catering industry of commercial users, humidity, high temperature, oil fume, steam, etc.After the table, the table does not read the card.(2) Battery problem: Due to the poor installation location of the IC card gas meter, it is generally in a high temperature and high humidity environment. Generally, the battery is naturally leaked and the electrolyte corrosion corrosion circuit board and electronic component are often caused, which affects the normal work of the instrument.It also affects the normal air use of users.On the other hand, the IC card table is generally used in alkaline batteries. This design brings the instability of use. If the battery power supply is unstable, it is easy to cause the valveThe voltage cannot open the valve, causing users to use it normally after purchasing Qi.
Intelligent gas meter structure
CPU card smart gas meter: · Micro -processor control circuit, valve, sensing device, gas meter, CPU card, etc.; the product design process structure is reasonable, the performance is safe and reliable, it is a smart card with high data transmission and high security.Gas meter, CPU card has the function of financial cards; in addition to the measurement and billing function of the smart gas meter, it also has the amount of gas, recording gas, various functional status display and sound prompts, restricting gas super flow, gas leakage of gas leakageIntelligent management and security prevention functions such as alarm (options);
Smart gas meter size
After investigation, the size of the smart gas meter includes G1.6, G2.5, G4 home watch series and G6, G10, G16, G25, G40, G65, G100 industrial watch series, as well as smart IC card gas meters, code type prepaymentsGas gas meter, direct read -type intelligent remote watch series.Its shape (wide × height × thick) has two specifications: 195 × 222 × 165mm3 (integrated), 200 × 307 × 165mm3 (split); the weight of these two specifications is:2.35kg (integrated), 2.68kg (split).However, the size of the smart gas meter produced by different manufacturers is also different.
Intelligent gas meter reading
Double -display gas meters in word wheels and liquid crystals. Such tables are mostly prefabricated IC card tables, which are combinations of word wheel count and liquid crystal display.The watch reading method is also a combination of the watchmaking method and the single LCD display. It can read the current remaining gas volume from the LCD display daily, and it can also be easily read from the word wheel counter.Under normal circumstances, this gas meter has 8 -bit wheels, of which the first 5 are black -shaped wheels, and the latter 3 is a red character wheel. Among themThere should be a small point on the nameplate, so you can see it at a glance.
What to think of smart gas meters
General home gas meters (non -industrial and commercial), when you face the gas meter, you can not read the number of three -character wheels on the right.The fourth digit starting from the right is a digit, and the unit is cubic meter.Such as: 00025698 In this number.698 three are small, you can not read.The fourth place 5 is a single digit.2 is ten digits.The reading of this table is: 25.698 cubic meters.Generally, the decimal position can be saved.So the reading of the table is 25 cubic meters.
