A tared weight W2 obtained by a measuring section 24 is equivalent to a buoyant force B the object to be measured M receives, i.e., the volume V of the liquid 22 displaced by the object to be measured M in the case the density of the liquid 22 is equal to one. はかり計量部24から得られた風袋を除いた重量W2は、被測定物Mが受けた浮力Bつまり液体22の密度が1であれば被測定物Mが押しのけた液体22の体積Vと同等となる。 - 特許庁
