Industries
Scarlet wireless anemometers have been applied to varieties of industries for wind speed & direction monitoring.
Renewable energy
Enhance planning and decision-making for renewable energy projects with ease. Measure wind speeds, identify optimal turbine locations, and evaluate areas for sustainable energy generation.
Construction
All construction project and especially high angle constructions operates under wind risk. Monitoring wind speed and wind direction is a vital issue when it comes to safe operation of construction sites.
Offshore
The rise in offshore wind farms needs accurate and easy-to-use wind measurement tools. Scarlet's wireless anemometer gives precise readings and is smaller and lighter, perfect for offshore use.
Building
Building skyscrapers is a common engineering project nowadays. Changeable climates also matters to workers at the construction site. Strong wind up there while under construction is a big threat for workers and might be fatal.
Port
Wind speed direction can significantly affect the position of a ship or oil platform. Regulations require that the vessels record weather data, including wind speed on a regular basis, with data displayed continuously on the bridge.
Outdoor events
Accurate wind data is required for both the build and setup process as well as during outdoor events. Monitoring of actual rigging loads, weight distribution and wind speed allows operators to make informed decisions regarding the stability of a structure.
