Simple device for measuring filling amount of perlite in LNG (Liquefied Natural Gas) storage tank

The utility model discloses a simple device for measuring the perlite filling amount of an LNG (Liquefied Natural Gas) storage tank, which comprises a support, a pulley, a graduated scale, a lead weight and a protective cover which are combined to realize the measurement of the perlite filling amount, the lead weight covered with the protective cover is put into a gap between a tank body and an inner wall plate through a tank opening during use, the graduated scale is slowly released, and the perlite filling amount is measured. When the lead weight covered with the protective cover is in contact with the cold insulation material, the reading of the graduated scale is read through the visual window, and measurement is completed. The thickness of the perlite needing to be filled in a long and narrow space can be measured, so that constructors can conveniently estimate the to-be-filled amount of the perlite. 本实用新型公开了一种测量LNG储罐珍珠岩填充量的简易装置，包括支架、滑轮、刻度尺、铅坠、保护罩组合实现珍珠岩填充量的测量，使用时将罩有保护罩的铅坠通过罐口放入罐体和内壁板之间的空隙中，缓慢释放刻度尺，直至罩有保
