Gill’s ultrasonic wind speed and direction sensor featured on the BBC’s daily TV programme, The One Show on Thursday 16th July 2015.
TheWindObserver which can measure wind speeds in excess of 200mph made its TV appearance during a feature on using ultrasonic technology to show how sound waves can be used to make measurements which are useful in real life situations. During the demonstration, Phil Bassindale from Bristol University used a hair dryer to simulate wind and showed presenters Matt Baker and Alex Jones, how the WindObserver records changes in wind speed when wind is present. The changing wind speed was displayed via a touch screen display from Observator instruments.
Watch the episode on the BBC iPlayer until 17/08/2015
ABOUT ULTRASONIC WIND MEASUREMENT
WindObserver sensors use the ultrasonic time of flight principle to ascertain wind speed and direction.
Opposing sets of transducers alternately send and receive ultrasonic pulses to each other. In still air these pulses travel at the same speed.
The wind speed affects the send/receive pattern of the pulses. Pulses in the direction of air movement will reach the opposing transducer more rapidly, whilst pulses into the wind will be delayed. The stronger the prevailing wind, the more prominent the effect will be.
Gill Instruments will be exhibiting at the 95th AMS Annual Meeting from 4-8 January 2015 in Phoenix, Arizona.
At AMS Gill will announce improvements in sonic temperature performance made throughout their range of industry leading 3-axis anemometers.
Gill 3-axis anemometers consistently out-perform other sonic anemometers in the measurement of 3-dimensional wind vectors and sensible heat fluxes and now following recent improvements all Gill 3-axis anemometers can benefit from improved sonic temperature performance.
Gains are the result of research using computational fluid dynamics and changes to the transducer stalk assembly processes. However for continuity, the transducer and stalk profile remains the same and wind measurements are not impacted.
Richard McKay, Gill Product Manager and Meteorologist reports “the gains we have made using CFD and assembly process improvements are small yet significant in the performance of sonic temperature throughout the 3-axis range. A key advantage is that these improvements maintain the continuity of design and we now have high performance in all conditions”.
To demonstrate the technical improvements, Richard McKay will be delivering a poster presentation entitled ‘Improvements in cold weather condition flux measurements with Gill 3-Axis Ultrasonic Anemometers’ at AMS on Wednesday 7th January between 14:00 and 16:00.
In addition to Gill’s anemometers, Gill will be displaying MaxiMet, their new range of compact weather stations to suit multiple application requirements which combines precipitation, solar radiation, wind, temperature, humidity and pressure, GPS and compass measurements.
