Improved Sonic Temperature Performance in 3-axis Anemometer Range

Apr 10 2015

The leading manufacturer of Ultrasonic Anemometers has announced improvements to the sonic temperature performance of their prestigious 3-axis anemometer range, improving the accuracy to greater than ±1% in readings between -18?C and +30?C.

Gill Instruments (UK) has achieved this significant gain using the National Physical Laboratory’s advanced sound profiling facility and research conducted using in-house computational fluid dynamics (CFD modelling) to examine the transducer production. The result is a new generation of transducer assembly, which benefits from small yet significant design changes to the assembly processes, whilst preserving the high performance of the existing transducer.

To maintain the integrity and continuity of the 3-axis anemometer range, Gill tightly controls the software, electronics, head geometry and transducer to ensure the changes are limited to only improving the performance of sonic temperature.

Used throughout the meteorological research and industrial industries, the popular anemometers simultaneously monitor turbulent fluctuations of wind and sonic temperature in order to accurately calculate sensible heat flux or wind load. With its improved transducer materials and assembly, the Gill anemometer range provides the best performing wind instruments on the market.

“Gill 3-axis anemometers consistently out-perform other sonic anemometers in the measurement of 3-dimensional wind vectors and sensible heat fluxes” says Gill Product Manager, Richard McKay. “Now following recent improvements all Gill 3-axis anemometers can benefit from improved sonic temperature performance. A key advantage is that these improvements maintain the continuity of design and we now have high performance in all conditions”.
