Abstract
This publication discloses a method and apparatus for measuring hydrometeors. According to the method, the mechanical impulses of hydrometers falling on a detection surface are measured. According to the invention, part of the measuring device () is used to perform a continuous measurement, in order to define a threshold value for an impulse and only after the threshold value is exceeded is the final part () of the measuring apparatus excited for measuring operations, in order to minimize the power consumption of the apparatus.
