Scintillometer BLS
The Boundary Layer Scintillometer BLS optically measures atmospheric
turbulence, heat flux and crosswind over spatial scales up to 5
kilometres. The spatial averaging results in significant advantages
over conventional point measuring.
With its proprietary technique, this large aperture scintillometer
sets a new standard in accuracy and ease of set-up. By accounting
for transmission changes, the BLS is capable of measuring even in
unfavourable and varying seeing conditions. The measured data are
stored in a Signal Processing Unit and read by a PC either in real
time or from memory. The BLS is fully weather resistant and supports
battery operation.
