Arrangement, the two pressure difference are air-flow dynamic pressure, and the dynamic pressure measured can obtain air velocity after formula scales and coefficient amendment.
Section: for circular cross-section, being divided into the concentric loop of N number of homalographic by gridding method equal area partition principle, then
Each annulus is divided into four parts of equal areas with orthogonal diameter, point is represented and is located at two concentric loops being divided into
On the intersection point of line of demarcation and perpendicular diameter；For rectangular section, with latitude and longitude by section be divided into several homalographics close to
The rectangle of square, each small cornerwise intersection point of rectangle are to represent a little.
It represents a little: selected when carrying out air measuring using gridding method equal area partition principle to be used in engineer application
Approximation replaces the measuring point of the section mean wind speed.
