PROBLEM TO BE SOLVED: To display a liquid level accurately and stably, by reducing the fluctuation in the liquid level display caused by generation of bubbles in a connecting tube, when using a differential pressure type level gauge for a tank for liquified gas. SOLUTION: The differential pressure type level gage 10 is connected to the tank 1 for liquified gas through each connecting tube 11, 13 on the low-pressure side and on the high-pressure side. A tip part 14, including an opening end 14a of a high-pressure side connecting tube 13, is inserted horizontally to the inside of a periphery of a bottom part of the tank 1. It is particularly preferable, that a plurality of small holes 14b, penetrating a wall surface of the connecting tube 13, be provided on an upper half part of the tip part 14 of the connecting tube 13.
