Product Overview:

SLS20 (ES), SLS20-A (ES), SLS40 (ES), and SLS40-A (ES) scintillation meters measure turbulence, heat flux, and momentum flux through pure optical means. Combined with other meteorological sensors, the system can determine latent heat flux or evaporation.

Each SLS series scintillation meter consists of a laser emitter pointing towards the receiver. The temperature fluctuations in the air cause changes in the intensity of light captured by the receiver. The scintillation meter evaluates these changes to generate turbulence information.

The line averaging on the optical path produces spatially representative data and excellent temporal resolution, which is a key advantage of data collected from traditional point sensors. The scintillation meter has high sensitivity and accuracy - without mechanical flow deformation or any moving parts.

The proprietary displacement beam technology of the SLS series scintillation meter can obtain mechanical turbulence flow (momentum flux, kinetic energy dissipation rate) without inputting any external wind data.
