1. A fluid level measurement system using a buoyant body, the fluid level measurement system comprising:
a guide part installed in a direction perpendicular to a bottom surface of a fluid storage tank, and provided with a space in which a fluid is allowed to move therein;
a buoyant body inserted into the guide part, and configured to float along a surface of the fluid inside the guide part;
a measurement part coupled to a top end of the guide part, and configured to measure a level of a surface of the fluid inside the fluid storage tank by transmitting a signal toward the buoyant body in an inner space of the guide part and then receiving a signal reflected from the buoyant body; and
at least one buffer member coupled to an upper end of a side surface of the buoyant body to prevent the buoyant body from being caught in the guide part when the buoyant body is ascended and descended inside the guide part,
wherein the buffer member is formed to protrude toward an inner circumferential surface of the guide part, and an outer radial end thereof is formed to have a predetermined radius of curvature, and
wherein the buffer member is made of polytetrafluoroethylene (PTFE).
