PURPOSE:To accurately measure a liquid level and to facilitate the repairing, the exchange or the like of a vertical gauge, by holding the vertical gauge to the holder provided to the bottom surface of a tank in a detachable manner. CONSTITUTION:A holder 28 consisting of a funnel shaped guide part 29 and a cylindrical body 28 is attached to the bottom surface 4 of a tank 1 and a holding part 33b for fixing a vertical gauge 13 is provided to the holder 27. In addition, an engaging part 17a is provided to the outer surface of the gauge 13 and held by the holding part 33b in a detachable manner to vertically provide the gauge 13 on the bottom surface 14. By this constituion, because the gauge 13 is not almost displaced with respect to the tank bottom surface 14 even if the tank is deformed, the change of the liquid level in the tank can be accurately measured and the repairing, the exchange or the like of the gauge can be easily performed. |
