This paper describes a simple approach to minimizing probe-induced flow distortion errors in a three-axis sonic anemometer. By separating the three axes, mutual interference between the transducers and supports in the three arrays is reduced. Only a transducer shadow correction determined from wind tunnel tests is needed to obtain measurements that are virtually insensitive to probe orientation relative to the mean flow. Preliminary results from a series of three atmospheric tests verify the effectiveness of this correction.

Weather monitoring network equipped with Lufft wind sensor VENTUS - Case Study
In 2010 we won a tender for 30 ultrasonic anemometers (as a part of meteorological weather stations). The National Weather Service of Mexico (CONAGUA) wanted to build weather stations in the southwest of Mexico (States of Chiapas and Tabasco). According to the customer, Ventus-UMB is a very robust, yet precise sensor with a very good price / performance ratio. Moreover, data transmission via the SDI-12 protocol is in the opinion of CONAGUA a great product advantage. So the customer decided to construct the...
Weather measurement in extreme conditions - Whistler Mountain - Case Study
Whistler Blackcomb mountain is a premiere winter resort in British Columbia Canada. Some months ago our subsidiary "LufftUSA" installed the first Ventus-UMB ultrasonic anemometer atop a main ski lift on the Whistler mountain. The first winter storm passed leaving the entire mountain and all mechanical equipment covered in snow and ice... except the Ventus-UMB. The Ventus-UMB continued to give accurate wind speed and wind direction data through the storm. Now there is a plan to install more Ventus-UMB sensors at...
Ultrasonic wind sensor for smart wind turbine control - Polaris / USA - Case Study
The American wind turbine manufacturer Polaris trusts for their wind turbine applications anemometers from Lufft. Over 50 wind turbines have already been equipped with our ultrasonic anemometers Ventus-UMB and V200A-UMB. Crucial in these applications is a high degree of precision and a long, maintenance-free useful life. In addition, controlling of the turbine complex requires a high frequency of data to provide the most efficiency. Our Ventus-UMB and V200A-UMB anemometers perform all this.
Mechanical vs. Ultrasonic Anemometers for Wind Turbine Control
What do you think? Does the replacement of mechanical wind sensors trough ultrasonic anemometers in wind turbine control pay off after less than a few years? Free Cost Benefit Analysis about Replacement of Mechanical Wind Sensors Anemometers are vital components of utility-scale wind turbines and determine the performance of the turbine’s output.In the market today, companies are transitioning to ultrasonic anemometers. These sensors contain no moving parts and are entirely electric, which reduces...
Case study - Barnsley Council
As part of their commitment to improving the energy efficiency of all homes and buildings within their borough, Barnsley Council contacted Logic Energy to see if they could assist Dearne Carrfield Primary School in discovering their “green potential” before investing in a renewable energy system. With solar thermal systems, wind, solar PV and biomass systems all an option, the school wanted a monitoring system that would measure various meteorological sensors to help them to decide on the most...
