Introduction
Interpretation of the core content of the standard
This standard constructs a complete technical framework for energy efficiency measurement in process industries, focusing on standardizing the application requirements of measuring instruments such as electricity meters and flow meters. Its technical points include:
| Technical dimension | GB/T41570-2022 | Traditional practice |
|---|---|---|
| Metering level | Energy-consuming unit/sub-unit/equipment three-level measurement | Single enterprise-level measurement |
| Data integration | Support XML/API/direct database connection | Manual meter reading is the main method |
| Equipment requirements | Mandatory communication interface and digital function | Mechanical instruments are the main method |
Key technological innovations
The standard first proposed a three-layer model (instrument layer/network layer/management layer) of the energy efficiency metering system architecture, requiring that equipment such as differential pressure flowmeters must meet the following requirements:
- Accuracy level must comply with GB17167 requirements
- Communication interface supports automatic data collection
- Traceability must be verifiable
Application case: Implementation in petrochemical enterprises
After a refinery deployed turbine flowmeters according to standards, it integrated steam energy efficiency data through the MES system and achieved:
- The metering point configuration rate increased from 68% to 92%
- Energy costs decreased by 7.3%
- Carbon emission data was automatically generated
Implementation Suggestions
The company should advance in stages:
| Phase I | Complete the energy efficiency metering network diagram |
| Phase II | Configure standard electromagnetic flowmeters and other equipment |
| Phase III | Establish an energy efficiency data center |
Pay special attention to the 6 management systems required in Chapter 10 of the standard, including the management specifications for the entire life cycle of measuring instruments.
