I. Software Functions
1. Calculate the orifice diameter according to GB/T 2624.2-2006/ISO 5167-2:2003 standards.
2. Supports both gas and liquid media.
3. Supports three pressure tapping methods: corner tapping, flange tapping, and pitch tapping.
4. Provides complete calculation results and verification.

II. Precautions
1. For gas media, the differential pressure limit should not exceed 25% of the operating pressure.
2. Calculation results must be verified against the applicable limits specified in the standards.
3. The calculation iteration accuracy of this program is 6 decimal places.
4. The calculation results are for reference only; practical applications require consideration of engineering experience.

III. Usage Tips
1. Use the common media function to quickly set fluid parameters.
2. Use the material database to select the linear expansion coefficients for pipes and orifice plates.
3. Use the parameter save/load function to save frequently used settings.
4. Calculation results can be exported in text or CSV format.
The software includes a built-in material database:
- Gases: 20 types such as air, nitrogen, oxygen, carbon dioxide, methane, natural gas, etc.
- Liquids: 28 types such as water, diesel, gasoline, kerosene, crude oil, lubricating oil, etc
