Vaisala WindCube Vertical Profiler
Remote sensing devices are lightweight and easily transportable, they do not require planning permission and can be applied both offshore and onshore to gather wind data from 40m to 300m in height, with up to 20 separate height measurements taken every second.
Coupled with Dulas’ robust remote power supply, and in field monitoring services, these LiDAR units can operate reliably in the field for years with regular refuelling and maintenance intervals.
Remote sensing devices can be deployed ahead of met masts and in conjunction with them to extend and enhance your data sets. Though it is widely held that terrain in the UK is too complex to allow for LiDAR only measurement campaigns currently.
Dulas is proud to be an authorised distributor of Vaisala WindCubes in the UK and Ireland.
Features & Benefits
- Embedded FCR correction for direct measurement in complex Terrain
- IEC compliance for contractual performance testing (IEC 61400-12-1:2017)
- 3-year warranty and maintenance with optional onsite maintenance
- Includes WindCube Insights cloud- based data management system
The industry-standard vertical profiling LiDAR for wind energy applications. Its highly accurate, rigorously validated data aids in wind farm development and operations, both offshore and onshore.
WindCube provides accurate wind measurement up to 300 meters over 20 simultaneously measured heights. The result is bankable data with a more complete view of the wind profile – both of which help you secure funding, reduce uncertainties and the cost of equity, and minimize risk.
WindCube data has been validated by hundreds of independent studies and is accepted by all international standards and guidelines. On complex terrain, it uses FCR – also validated by formal studies.
WindCube is IEC-compliant for contractual performance testing, and it is well-suited for continuous wind monitoring, power performance verification, grid-loss compensation, and more.
WindCube units are simple and fast to deploy, with few, if any, permitting or regulatory challenges. The system can stand alone or be co-located with a met mast.
