Patent ID: 10620231

Abstract:
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 includes 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. An evaluation unit, determines at least one component of a wind velocity vector and/or the velocity of sound, 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 transmittor and the sound detection surface of the at least one receiver to cover the distance of this measuring section. At least one measuring section is provided between a first sound emission surface of a first transmitter and a first sound detection surface of a first receiver arranged approximately vertical to the earth's surface and the first sound emission surface and/or the first sound detection surface is inclined compared to the horizontal.
