General Requirements for Liquid Level Gauges in Carbon Dioxide Storage Tanks:

1.Select based on the medium, maximum allowable working pressure, and temperature of the carbon dioxide storage tank.
2.Prior to installation and use, conduct a hydraulic test at 1.5 times the gauge’s nominal pressure for CO₂ storage tanks with a design pressure below 10 MPa. For tanks with a design pressure of 10 MPa or higher, perform a hydraulic test at 1.25 times the gauge’s nominal pressure.
3.For CO₂ storage tanks containing media below 0°C, select frost-proof level gauges.
4.For outdoor use in cold regions, select jacketed or insulated level gauge structures.
5.For liquefied carbon dioxide storage tanks that store specific media, such as those containing explosive or highly hazardous toxic substances, the liquid level gauges of the liquefied carbon dioxide storage tanks must be equipped with leak prevention protection devices.

6.In cases where there are requirements for the stability of liquid level indication, floating liquid level meters must not be used. The liquid level meter should be installed in a position that is easy to observe. If observation is inconvenient, auxiliary facilities should be added. Large carbon dioxide storage tanks should also be equipped with a centralized control system and alarm devices. The liquid level meter must have clear markings indicating the maximum and minimum safe liquid levels.
