    • An air flow measurement device includes an air pipe securely formed inside the cylindrical tube, a first measuring tube securely formed inside the cylindrical tube and having a first open end located at an inner side face of the air pipe so as to measure radial pressure of air flowing through the air pipe and a second open end extending out of the cylindrical tube. An L shaped measuring tube is securely formed inside the cylindrical tube and has a first open end located at the inner side face of the air pipe so as to measure axial pressure of air flowing through the air pipe and a second open end extending out of the cylindrical tube.
    • 气流测量装置包括:密封地形成在圆筒形管内的空气管,第一测量管,牢固地形成在圆筒管内,并且具有位于空气管的内侧面的第一开口端,以便测量空气的径向压力 流过空气管和从圆筒形管延伸出的第二开口端。 L形测量管牢固地形成在圆柱形管内,并且具有位于空气管的内侧面的第一开口端,以便测量流过空气管的空气的轴向压力,以及第二开口端延伸出 圆柱管。
