LeWL Wind logger


The LeWL is a vital component in the initial wind site assessment process and is used worldwide by professionals for small scale projects.

  • Established design and reliability.

Manufactured in the UK under ISO 9001 standards.

  • Comprehensive system functionality in a simple to use compact design.

The Windlogger allows 2 simultaneous inputs for anemometers and a separate wind vane –this enables the user to obtain critical information about the site such as wind shear and performance by measuring at different heights (sometimes a 5 meter difference can make a 500kWh per month difference on the same wind turbine)

  • Fast and detailed data recording

Simple import into any professional wind data analysis program. The windlogger allows fast logging and flexible intervals to allow greater detail for long term wind data tracking.

  • How do I ensure I get the most from my investment?

The LeWL windlogger measures all the required wind data values to help chose not just the right site but the right wind turbine.
