total pressure loss ratioとは 意味・読み方・使い方

To measure flow velocity from a static pressure and a total pressure as a pitot tube system by suppressing a contraction ratio in a small range and reducing a pressure loss in a large flow rate area, while expecting pressure recovery as a venturi tube, and to enlarge a measuring range of the static pressure or a differential pressure capable of measuring a flow rate highly accurately.例文帳に追加

ベンチュリ管として圧力回復を期待できる一方で、絞り比を小さい範囲に抑え、大流量域における圧力損失を少なくしてピトー管方式としての静圧と全圧からの流速測定を行い、かつ高い精度で流量測定が可能な静圧あるいは差圧の測定範囲を大きくする - 特許庁
