Abstract: According to the principle of the interference of two beams and the buoyancy law,the principle and design of one buoyancy balance for measuring little mass change of a body is discussed.The result shows that sense quantity,sensitivity,maximal load,and accuracy rating of the buoyancy balance are superior to the current balance,and the buoyancy balance has wide-ranging applied domain.

Key words: buoyancy balance, principle, design
