method and device for measuring prevailing weather and meteorological visibility.

摘要

The present invention concerns a method and assembly for measuring prevailing weather and meteorological visibility. According to the method an optical scattering-type measurement instrument (1, 2) is used for determining the apparent volume of precipitation in a measurement space (7). According to the invention the apparent volume of precipitation is measured in measurement space (7) having a volume of less than 0.2 liters, and simultaneously with this measurement of apparent volume of precipitation, also the water quantity related to the measurement space (7) is measured. The implementation according to the invention makes it possible to determine both the type and rate of precipitation. IMAGE
