Gill Group

Gill Instruments builds meteorological instrumentation for those who can’t afford guesswork.
For 40 years, we’ve taken a deliberately uncompromising approach to meteorological and environmental measurement. No fragile parts. No inflated promises. No performance that only works on paper. Our ultrasonic anemometers and weather stations are engineered for operators who need accurate data they can stake decisions on – the kind of decisions that move markets, protect assets or keep operations running when conditions turn hostile.
We sit at the heart of some of the world’s most demanding operations: stabilising power grids, supporting dynamic line rating, guiding renewable assets, informing aviation decisions, and powering smart-city intelligence. If you’re working in a sector where the environment dictates performance, chances are you’re already using Gill, directly or indirectly.
We’re not in the business of “nice-to-have” sensors.
We build the kit operators rely on when accuracy, durability and trust genuinely matter.

Why Gill Instruments
Meteorological sensors provide utilities real-time insight into the environmental conditions that influence grid performance and risk.
They can track factors such as temperature, wind speed, humidity, solar radiation and precipitation, which directly affect the thermal capacity of transmission lines.
This data can support proactive decisions allowing operators adjust line ratings, anticipate fire weather, understand how assets respond to changing conditions and protect infrastructure from environmental stress. It also helps them correlate environmental factors with asset behavior, enabling predictive maintenance, reducing downtime, improving reliability and reducing operational costs.
Our anemometers and compact weather stations are built for harsh environments. With no moving parts, they are simple to install and need very little maintenance, which makes them ideal for remote or hard-to-reach sites.
