Abstract
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.
