Large Aperture Scintillometer
商品詳細介紹Product Introduction
Large Aperture Scintillometer
The Scintec BLS900 Large Aperture Scintillometer measures atmospheric
turbulence, heat flux and crosswind over path lengths between 250 m and
6000 m. As part of a meteorological station it can also be used to determine
the evapotranspiration over extended areas.
A scintillometer senses turbulence between an optical transmitter and
a receiver. The operation principle is based on the modulation of light by
atmospheric refractive index fluctuations in the air. The phenomenon is
called scintillation and is the reason why stars twinkle at night.
Compared to conventional turbulence measurements with point sensors,
scintillometers gather spatially representative results with lower statistical
scatter and shorter averaging times.
The Dual-Disk Design of the BLS900 provides for instantaneous corrections
of absorption fluctuations, saturation of scintillation and outer scale effects.
This results in significantly higher data quality and increased measurement
ranges. All BLS Series scintillometers use LED arrays. Wide emission angles
virtually eliminate the need for transmitter alignment and maintain high
data accuracy even when used on towers which are prone to vibration.
