How to choose a level gauge for pressure vessels?
1. It should be selected properly based on the medium, maximum operating pressure, and temperature of the pressure vessel. 2. Before installing and using a level gauge, level gauges for low- and medium-pressure vessels shall undergo a hydrostatic test at 1.5 times the nominal pressure of the gauge; level gauges for high-pressure vessels shall undergo a hydrostatic test at 1.25 times the nominal pressure of the gauge. For pressure vessels operating at temperatures below 3.0°C, frost-proof level gauges should be used. 4. For level gauges used outdoors in cold regions, jacketed or electrically heated level gauges should be selected. 5. For applications requiring a stable liquid level indication, float-type level gauges should not be used. 6. Glass plate level gauges shall not be used in mobile pressure vessels.

The choice depends on the medium stored in the pressure vessel, the storage temperature, the physicochemical properties of the medium, and so on.
