Selection Steps and Suggestions
Follow these steps to quickly complete the selection:
- Confirm process conditions: medium, temperature, pressure, flow range, explosion-proof requirements, etc.
- Select liner and electrode material according to medium corrosiveness.
- Select process connection and design options according to pipeline standards.
- Select power supply, output, and firmware version according to power supply and communication requirements.
- Select housing, electrical connection, and sensor options according to installation environment.
- Select calibration, testing, and other certification options according to certification requirements.
- Check the selection codes to ensure compatibility of all options.
If there are special requirements, you can choose special type codes (such as 9, 999, etc.) and define the TSP number.
Frequently Asked Questions (FAQ)
1. How to choose the explosion-proof rating?
Choose according to the hazardous gas classification of the installation area, e.g., select AA for non-explosion-proof场合, C6 for CSA certification.
2. How to choose the liner material?
Hard rubber is suitable for neutral media such as water, PTFE has strong corrosion resistance, and polyurethane has good wear resistance.
3. What is the difference between calibration accuracy 0.2% and 0.5%?
0.2% has higher accuracy and is suitable for trade settlement and other demanding occasions; 0.5% is suitable for general industrial measurement.
4. How to interpret the process connection code?
The first letter of the code indicates the flange standard, the number indicates the pressure rating, and the letter K/S indicates carbon steel/stainless steel.
5. How to handle special type options?
After selecting the special type code, provide the TSP number to specify the exact specifications.
