PURPOSE:To measure accurately the gas contained in a gas storage by permitting a diaphragm to expand and contract in compliance with vertical movement of a partition plate held horizontally and by obtaining the level of partition plate with a high level meter. CONSTITUTION:A partition plate 12 makes vertical movement smoothly along a side plate 18 being held horizontally by a guide rail or a balance device 20. A diaphragm 15 expands and contracts in compliance with the motion of the partition plate 12 and, also, the inside cross area of a gas storage room 16 is maintained approximately constant, so that amount of the gas in the gas storage room 16 increases proportional to the level of the partition plate 12, which gives that determination of the level of partition plate 12 with a high level meter 25 will allow accurate measurement of gas amount contained in the gas storage room 16. |
