Ultrasonic Anemometer And Method For Determination Of At Least One Component Of A Wind Velocity Vector Or The Velocity Of Sound In The Atmosphere

摘要

Described is an ultrasonic anemometer (7) as well as a method for determination of at least one component of a wind velocity vector and/or a velocity of sound with at least one sound transducer at least temporarily working as a transmitter (1, 2, 3, 4, 5, 6, 15, 16) with a sound emission surface for emitting sound waves and at least one sound transducer at least temporarily working as a receiver (1, 2, 3, 4, 5, 6, 15, 16) with a sound detection surface for at least partially receiving the emitted sound waves, and with an evaluation unit, which, based on a recorded transit time, which the sound waves require on a measuring section located between the sound emission surface of the at least one transmitter and the sound detection surface of the at least one receiver to cover the distance of this measuring section, determines at least one component of a wind velocity vector and/or the velocity of sound.;The technical solution described is characterized by at least one measuring section between a first sound emission surface of a first transmitter and a first sound detection surface of a first receiver being arranged approximately vertical to the earth's surface and the first sound emission surface and/or the first sound detection surface being inclined compared to the horizontal.
