Overview General design Stave height tuning Setting of the box Fan DAQ Flow-meter

General Design 1770mm Flow Formed by: - a fixed set  Fan + Set with the Stave - a moving box

Stave height tuning

Setting of the box a) Maximum displacement of the box

Setting of the box  the three combinations can be tested

First layer

Second layer

Third layer services are not considered

Setting We can also adjust the stave to the flux in 3 positions thanks to the pin holes: - 90° - 45° - 0°

Flow-meter Waiting for the quote It seems to be ok in terms of integration, wind speed range, DAQ compatibility, precision (+/-3% with the optional high precision). It’s quite expensive, the price should be around ~700 euro per sensor. Small problem: the orientation of the sensor has to be precise (+/-3°).
