Claims (1)
面に設けた測圧孔から導かれる圧力を検出して流
れの方向、速さを測定する多孔ピトー管において
、上記円筒体の同一円周断面部に等間隔で６ケ所
以上８ケ所以下の測圧孔を設けたことを特徴とす
る多孔ピトー管。 In a porous pitot tube, the direction and speed of the flow are measured by inserting a cylindrical body into the flow and detecting the pressure introduced from the pressure measurement hole provided on the outer wall of the cylindrical body. A porous pitot tube characterized in that pressure measuring holes are provided at equal intervals in a circumferential cross section at six or more locations and at most eight locations.
