The fluid-dynamic pattern around the sensor (2) of a wind speed and direction raeasuring apparatus, which comprises support bars (10) around the sensor (2) is disturbed by these support bars, so that the measured speed of a given wind is dependent on its direction. In the past, this phenomenon was compensated electronically, but the compensation needed to be adapted to any different geometry that was actually used in a particular wind meter. The present invention proposes to arrange the support bars (10) in inclined manner with respect to the orientation of the sensor (2). Thus, the flow pattern of the wind between the support bars (10) and the sensor (2) becomes largely independent from the direction of the wind. |
