发明名称 METHOD FOR DETERMINING THE VOLUMETRIC PROPORTION OF LIQUID WATER AND THE DENSITY OF SNOW, AND DEVICE FOR CARRYING OUT THE METHOD
摘要 The invention relates to a method for determining the volumetric proportion of liquid water and the density of snow, and to a device for carrying out said method. The inventive method is designed in such a way that interference can be excluded by the measuring system itself. A probe consisting of at least three electric conductors (1, 2) which are arranged parallel to and at different distances from each other is positioned before snowfall or placed in snow which has already fallen (3). Two of the conductors are subjected to the action of an electromagnetic signal with a frequency for which the dielectricity coefficients of water and ice are known and the dielectricity coefficient of the snow is then determined with an inevitable air gap around the probe, based on the transmission behaviour of the electromagnetic signal.
