Force deflection anemometer having improved accuracy

摘要

An anemometer having no moving parts and a sensing head with various emboents that improve the overall performance of the anemometer is disclosed. The sensing head of the anemometer generates an aerodynamic drag force when subjected to a dynamic pressure in the form of a moving fluid, such as wind. The aerodynamic drag force is translated to a deflectable column having a plurality of strain gauges thereon, each of which produces an electrical output voltage that is proportional to the wind speed. The sensing heads of the anemometer of the present invention reduced the velocity and directional error measurement parameters as well as reduce the angle of attack error.
