Residential Aluminum-Case Diaphragm Gas Meter Specifications and Models
Understanding the technical parameters of a gas meter is essential before specifying it for a project, because each model is designed to serve a particular range of household appliances and consumption profiles. Apexmetertech offers three primary residential models—G1.6, G2.5, and G4—each calibrated to handle different maximum flow rates while maintaining a consistent level of metering precision. The G-series designation follows international standards, ensuring that these meters can be deployed in markets that reference European or ISO performance norms without requiring extensive requalification work.
The table below summarizes the core specifications of each model, providing a quick reference for engineers and procurement teams when they compare the Residential Aluminum-Case Diaphragm Gas Meter options available in the lineup.
Parameter | G1.6 | G2.5 | G4 |
Flow Range (Qmin – Qmax) | 0.016 m³/h – 2.5 m³/h | 0.025 m³/h – 4 m³/h | 0.04 m³/h – 6 m³/h |
Operating Temperature | -25 °C to +55 °C | -25 °C to +55 °C | -25 °C to +55 °C |
Maximum Working Pressure | 50 kPa | 50 kPa | 50 kPa |
Pressure Loss at Qmax | ≤ 200 Pa | ≤ 200 Pa | ≤ 250 Pa |
Weight (Approx.) | 1.8 kg | 1.9 kg | 2.1 kg |
Each specification directly influences real-world performance in meaningful ways. The flow range defines which households the meter can serve, with G2.5 being the most common choice for standard apartments that run a cooking stove and a water heater simultaneously. Operating temperature tolerance determines whether the meter can be safely installed outdoors in climates with extreme seasonal swings, while low pressure loss ensures that downstream appliances receive adequate gas supply pressure even at peak consumption. Finally, the lightweight aluminum construction keeps total weight under roughly two kilograms across the range, simplifying handling during installation and reducing the structural load on wall-mounted brackets.
It is also worth noting that accuracy class 1.5 applies across all three models, meaning the measurement error stays within ±1.5 percent across the entire operating envelope in most flow conditions. This high-precision metering standard protects both the utility and the end customer, minimizing the risk of underbilling or overbilling over the service life of the equipment.

Core Product Advantages of the Aluminum-Case Diaphragm Gas Meter
This meter series' engineering choices translate into several distinct advantages that matter over a typical twenty-year deployment horizon. First and foremost, the housing is manufactured from a high-strength aluminum alloy, which delivers an excellent strength-to-weight ratio compared to traditional cast iron casings. This material selection makes the meter noticeably easier to transport, handle, and install while retaining the rigidity needed to protect the internal diaphragm mechanism from external impacts and deformation over time.
Corrosion resistance is another defining strength of the aluminum enclosure, and it is particularly relevant for coastal installations or industrial zones where salty air and atmospheric pollutants accelerate degradation of unprotected metals. The alloy surface is further treated to withstand humidity, temperature cycling, and occasional condensation, ensuring that the meter body retains its structural integrity and appearance for many years without repainting or frequent maintenance. Combined with high-precision metering at accuracy class 1.5, these properties result in a product that operates reliably from the first day of service and continues to do so through the full lifecycle.
Beyond mechanical durability, modern utilities increasingly require meters that can participate in automated reading infrastructure. Both the G1.6, G2.5, and G4 models are fully compatible with AMR/AMI smart metering systems, because the base meter can be equipped with pulse output modules or communication interfaces that relay consumption data to collection networks. This built-in futureproofing allows distributors to deploy conventional meters today and upgrade them to smart gas meter functionality as their network modernization roadmap matures, avoiding the cost of premature meter replacement and protecting their capital investment.

Installation and Usage Notes for Sustained Accuracy
即使是制造精良的燃气表，如果安装不当，也可能无法达到最佳性能，因此遵循正确的方向和定位指南至关重要。此类膜式燃气表安装时，流量方向箭头应与实际气流方向一致，表体应按照制造商指定的方向安装，通常表盘面应便于读数。安装位置必须留有足够的空间以便日常检查，同时燃气表应避免直接暴露于通过管道系统传递的过度振动或机械应力之下。
Operating conditions also deserve careful attention, because the meter's accuracy and longevity depend on the gas remaining within the specified temperature and pressure windows during normal service. The ambient temperature range of -25 °C to +55 °C covers most residential environments, but installations in unheated outdoor cabinets should consider local climate extremes. Similarly, the maximum working pressure of 50 kPa must never be exceeded, and upstream filtration is recommended if the supply gas contains particulate contamination that could accelerate wear on the internal measuring chamber and affect the continued reliability of the diaphragm mechanism.
Routine maintenance requirements are minimal, which is one of the major attractions of this meter type for volume-driven operations. Annual visual inspections for casing damage, leaking connections, or signs of tampering are generally sufficient, while internal servicing is rarely required within the expected service interval. When issues do arise, common troubleshooting begins with verifying that the gas supply valve is fully open and that no blockage exists in the downstream piping before suspecting the meter itself. If a reading anomaly persists after these checks, contacting the manufacturer's technical team is recommended to diagnose potential mechanical issues rather than attempting field disassembly, which could void the calibration warranty.
