What are the dimensions of a gas meter?

The dimensions of a gas meter are typically 210-220mm in width and 220-230mm in length. From the outside, only a small glass window with a numbered roller can be seen on the gas meter. The roller displays seven digits, with four black digits before the decimal point and three red digits after. The automatic cumulative function of the gas meter allows households using natural gas or pipeline gas to easily track their gas consumption, enabling them to pay based on the monthly consumption measured in cubic meters. Gas metering devices include the G1.6, G2.5, and G4 series for household use, as well as the G6, G10, G16, G25, G40, G65, and G100 series for industrial use. Additionally, there are smart IC card gas meters, code-based prepayment gas meters, and direct-reading smart remote transmission meter series. The gas meter operates on the same principle as an old locomotive, utilizing gas pressure to perform external work and drive the roller counter. The technology used in gas meters is similar to that in steam engines, allowing the diaphragm and hard core to continue moving when they reach the far left or right. Specifically, two sets of bellows and diaphragms are used, with their hard cores connected by rods to the same vertical shaft. This shaft has two cranks set 90 degrees apart, ensuring that the movements of the two hard cores are half a step out of phase. When one reaches its limit, the other is at the midpoint, ensuring continuous operation without stopping.
When installing a gas meter at home, I paid special attention to its dimensions. Standard household gas meters typically have a width ranging from 20 to 25 centimeters, a height of 10 to 15 centimeters, and a thickness of around 10 centimeters, depending on the brand. Compact models might be slightly smaller. The installation location is crucial—it's best to place it near the gas stove in the kitchen, leaving a 5-centimeter gap for ventilation to prevent heat buildup and safety hazards. I remember the technician reminding me to regularly check the readings for leaks. A meter that's too small may restrict gas flow, while one that's too large takes up unnecessary space. Measuring the wall space at home before choosing a meter is wise, as these devices are used for many years, and proper planning can save a lot of hassle. If the size doesn’t match, you might need to re-drill and reinstall, wasting time and money, so I always check the dimensions on the meter’s backplate or manual to confirm.
I've modified gas meters several times, and size is something that can't be overlooked. The most common household types are 15 to 20 cm wide and 12 to 17 cm high, with a 3 to 5 cm clearance needed for heat dissipation during installation. Overcrowded space may lead to overheating malfunctions. I usually start by measuring the width and depth of the installation area with a tape measure, noting the position of pipeline connections. When selecting a meter, consider the height of the reading window for convenient daily checks. Many newer meter designs are more compact—for example, energy-saving models may be half as thick—but the pipeline connection points might differ, requiring checks on screw hole alignment to prevent gas leaks. For safety, always test for airtightness after installation; improper sizing can easily cause issues. Replacing old meters with smaller ones in older homes is a great space-saving solution—don't just focus on price.
Gas meter dimensions are influenced by model and usage, with household widths commonly ranging from 10-20 cm and heights from 8-15 cm. During installation, I refer to the manufacturer's manual for verification, ensuring the location is well-ventilated. Standard dimensions guarantee stable and safe airflow, with tight pipe connections to prevent leaks. Excessively large sizes are impractical as they occupy unnecessary space. Updated meter sizes feature optimized designs, such as slimmer models suited for compact kitchens.
