A float gauge module for pressure vessel is provided that the exposure of the minute gas through an indicator is blocked by maintaining the airtight. A float gauge module(100) for pressure vessel comprises an indicator(210) which indicates the movement degree of a float(220); a float gauge(200) which includes the float and the indicator that are supported by a supporting rod(230); a pressure plate(300) which surrounds the side circumference of the indicator of the float gauge, and has a plurality of assembling holes(302); boss plates(400) in which a flange part(410) adhered to the inner surface of the pressure vessel is formed in the lower part of the base portion(420); an indicator see-through window(530) which passes through the upper wall center; and a cover which has a sidewall(520) covering the circumference of indicator(500). |
