VDI 3786 Part 12:2019 Edition

The standard applies to the measurement of the wind vector and the virtual temperature with high temporal resolution, and to the determination of turbulent variables, e.g. in measuring tasks for the estimation of the dispersion situation regarding air quality for installations requiring approval according to BImSchG and TA Luft, in the monitoring of nuclear facilities and in many agrarian meteorological, forestry and general micro-meteorological questions. Thus, ultrasonic anemometers are part of the corresponding measuring stations. Furthermore, ultrasonic anemometers can replace conventional mechanical anemometers in the determination of the average wind vector and can also be used in stations both for climate and weather measurements according to the international standard (WMO No. 8). The standard in particular addresses assessors, representatives of authorities and scientists.
