ABSTRACT:
Apparatus for measuring windspeed and/or direction with the aid of a sound-wave transmitter (25) and a receiver (25) for receiving reflected sound waves, in which apparatus the sound waves (25a) are transmitted in a multiplicity of directions, and in which a compilation of the measuring result obtained with each measuring operation gives a measure of the speed and/or direction of the wind. The transmitter and/or the receiver (25) are arranged to rotate, so that measuring results from a plurality of measuring locations can be evaluated. The transmission lobe (25a) is inclined in relation to the axis of rotation of the transmitter and/or receiver.
