Measurement for the places other sensors can't survive.
Gill ultrasonic wind sensors and weather stations work in the world's most demanding environments, from offshore platforms and wind farms to airport runways, defence ranges, and the research vessels tracking climate change. Find your industry below.
Built for conditions other sensors can't survive.
Ultrasonic measurement has no moving parts, no bearings to wear, no cups to ice over. That's why Gill sensors run for 15 to 20 years. Many run even longer.
Nine industries. One engineering philosophy.
Specifying sensors for a specific deployment?
Three technical guides for the applications engineers ask us about most. Each covers the full product range, integration notes, FAQs and the trade-offs that matter.
Three projects we're proud to be part of.
Mayflower Autonomous Ship (MAS400)
Gill MaxiMet GMX500 on board the AI-driven autonomous ship that crossed the Atlantic without a crew.
Monitoring wind at the Burj Khalifa
WindSonic sensors at the world's tallest building, feeding structural safety data 828 metres above Dubai.
Saildrone sets a world wind speed record
Gill WindMaster on board the Saildrone USV that recorded the highest wind speed ever measured by an unmanned vessel.
Why engineers pick Gill
Six things our customers say again and again, across four decades of measurement.
40+ years of ultrasonic
Gill pioneered the ultrasonic anemometer. Four decades of refinement sit inside every sensor we ship today.
Chosen for headline projects
Specified on the Mayflower Autonomous Ship, the Saildrone world-record USV, the Burj Khalifa, and Plymouth Marine Laboratory.
No moving parts
Ultrasonic measurement eliminates the wear, bearing drift, and icing failures of mechanical cup anemometers.
Designed and built in the UK
All products engineered and manufactured in Lymington, Hampshire. Quality-controlled end to end.
King's Award for Enterprise
Awarded for International Trade and presented by HM Lord-Lieutenant of Hampshire.
UKAS-accredited calibration
Through Labcal, the group's independent calibration laboratory, so the data you rely on is verifiable.
