Metrological support of ultrasonic thermoanemometers for measurement of pulsation properties of meteorological parameters

Resumo

Metrological support of production and exploitation of ultrasonic thermoanemometers (anemometers/thermometers) (UTA) for measurement of meteorological parameters of the atmospheric boundary layer is considered in this work. Necessary UTA tests are described: in an wind tunnel, zero wind chamber, climatic chamber, and in a pressure chamber. Parameters of the ADS-60 wind tunnel, which has been designed at Institute of Monitoring of Climatic and Ecological Systems, Siberian Branch, Russian Academy of Sciences, are given. ADS-60 was designed for testing UTA against rules of Russian Federal Service for Hydrometeorology and Environmental Monitoring for wind velocity. A mobile complex designed for checking technical parameters of UTA in field conditions is described.
