WindLogger with 2 anemometers & wind vane

Estimated dispatch time between 1 and 5 days


  • This kit utilises the new WindLogger feature of having 2 anemometer inputs recording data simultaneously, so you can measure the wind speed at two different heights.

    What is this good for? Mainly to calculate wind shear or more commonly used to extrapolate wind speed at a higher heights. Imagine you want to know the wind speed at 23 meters but your wind mast only reaches up to 18 meters. You could connect the top anemometer at 18 meters and the second one at 12 meters for example. With these two values you could extrapolate your wind speed at 23 meters without having to physically measure it. Just keep in mind it is not recommended to extrapolate more than 2/3rds of the top measurement point. 

    This kit brings all the key features from a professional wind monitoring system but at an entry level price. The kit comes with:

     • new LeWL WindLogger
     • 1 x Combined anemometer with wind vane, with 13 meters of cable and attachment support for the mast
     • 1 x Vortex anemometer with 10m of sensor cable
     • Quick guide installation
     • Industrial grade batteries and industrial grade microSD card.

Customer Questions

Ask Question
Q: What is the closest interval this logger can record?

A: 10 seconds, we recommend this setup only for short periods of time as it generates a lot of data and consumes much more battery. The other options are 1 minute and 10 minutes recording. The sampling rate is discrete.

Q: We need to get longer cables since our installation will be on an existing 22m pole. Do you have longer cables available within this set, i.e. 25m (including reserve)? Thanks and best regards!

A: The standard cable is 13m long. We don't usually recommend extending the cable as it can be an entry point for water ingress if it has not been terminated right.
