Gill Instruments improves performance of 3-axis anemometers

Gill Instruments has improved the sonic temperature performance of the company’s 3-axis anemometer range to an accuracy of greater than ±1% in readings between -18°C and +30°C. The improvement has been achieved by using the US National Physical Laboratory’s advanced sound profiling facility as well as research using in-house computational fluid dynamics - CFD modelling - to examine transducer production.

8134 Gill Instruments has improved the sonic temperature performance of the company’s 3-axis anemometer range to an accuracy of greater than ±1% in readings between -18°C and +30°C. The improvement has been achieved by using the US National Physical Laboratory’s advanced sound profiling facility as well as research using in-house computational fluid dynamics - CFD modelling - to examine transducer production.

Anemometers are used throughout the meteorological research and industrial industries. They simultaneously monitor turbulent fluctuations of wind and sonic temperature in order to accurately calculate sensible heat flux or wind load.

Gill claims the result is a generation of transducer assembly that benefits from small yet significant design changes to the assembly processes at the same time 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 changes are limited to improving only the performance of sonic temperature.

“Gill 3-axis anemometers consistently outperform other sonic anemometers in the measurement of 3-dimensional wind vectors and sensible heat fluxes” said Gill’s 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”.

    British meteorological instrument manufacturer Biral has launched what it says is “a very competitively priced” transportation road weather sensor (RWS-20). The sensor monitors visibility and obstruction to vision for road transport applications. It has been manufactured to allow easy integration with any road weather information system but it has been developed specifically for the harsh roadside environment. The RWS-20 is based upon Biral’s SWS range of visibility sensors, sharing many of its advanced tec

    Quicker, better, more cost effective materials testing - Kristina Smith writes. Most developments in materials testing technology involve updating and upgrading existing machines, either to meet changes to standards or to satisfy new needs in the market. And occasionally, a manufacturer will come up with something completely new. PUMA - the precision unbound materials analyser - falls into the latter category. It has been developed by Cooper Research Technology and Nottingham Transportation Engineering Cen
