Introduction
Interpretation of GB/T 26794—2023 Standard for Counters for Gas Meters
1. Background and significance of standard revision
GB/T 26794—2023 is an important standard for the gas meter industry, replacing the old version GB/T 26794—2011. This revision mainly updates the technical requirements and test methods to adapt to the needs of industry development:
- The scope of application has been expanded to cover counters for diaphragm, ultrasonic and thermal mass gas meters
- Added a new classification of counters, and clarified the technical requirements for mechanical, electronic and combined types
- Optimized environmental adaptability requirements and improved product reliability
2. Counter classification and design requirements
Based on the structure and function, counters are divided into three categories: mechanical counters, electronic counters and a combination of the two. The design requirements for various counters are as follows:
| Category | Design features | Applicable scenarios |
|---|---|---|
| Mechanical counter | Gear transmission, digital wheel display, simple and reliable structure | Applicable to medium and low flow gas meters |
| Electronic counter | Based on microprocessor, support storage and display functions | Applicable to high flow and smart gas meters |
| Combined counter | Integrates mechanical and electronic technologies, with high precision and reliability | Applicable to complex working conditions |
3. Comparison of key technical requirements
The new standard has made important updates to the technical requirements for mechanical and electronic counters. The following is a comparison of key indicators:
| Item | Mechanical counter | Electronic counter |
|---|---|---|
| Counting capacity | ≥99,999.999 m³ | ≥9,999,999.9 m³ |
| Environmental adaptability | High and low temperature resistance, humidity and heat resistance, impact resistance | EMC test, explosion-proof performance |
| Display requirements | Clear and discernible, no ghosting | High resolution, support self-test function |
4. Implementation Suggestions
Manufacturers: Before the new standard takes effect, it is recommended that companies do the following:
- Update product design and production processes to meet the requirements of the new standard
- Optimize the test process to ensure that environmental adaptability tests cover all working conditions
- Strengthen quality control, especially the inspection of counting capacity and display accuracy
- Train employees on the new standard to ensure accurate understanding and implementation of technical requirements
