On Determining the Melted Water Content of Snow by Dielectric Measurements (Zur Bestimmung des Schmelzwassergehaltes des Schnees durch Dielektrische Messungen),

Abstract

By measuring the capacity of a plate condenser filled with a mixture of snow and water, one is able to determine the water content of this mixture. Capacity is measured with a bridge in which the condenser to be measured is substituted. The condenser's plates are sealed in plexiglas so as to insulate them for direct current. The experiments showed the capacity and the loss (phase) angle to be a function of frequency in the range of 1,000 to 100,000 Hz.
