Level gauge, pressure vessels shall comply with the provisions of the relevantstandard, and shall meet the following requirements:
A. Media should be based on the pressure vessel, the maximum working pressureand temperature of the correct selection;
Two. Before installing and using low pressure vessel level gauge, hydrostatic testshould be the total nominal pressure of 1.5 times the surface; level gauge, high-pressure container with the surface meter of 1.25 times nominal pressure hydrostatic test should be carried out ;
3. Antifrost liquid level meter should be used in pressure vessels on the mediacontaining 0 ℃;
4. Outdoor use of the cold regions of the level gauge should be used in the folderlevel gauge of the dwelling or insulation structure;
5 For flammable, toxic level of extreme and highly hazardous liquefied gas mediumpressure vessel plate or automatic level gauge should be used, and should preventleakage protection device;
