Automatic rain gauge

摘要

An automatic rain gauge or pluviometer comprising a first receiver for receiving dry fallout; a second receiver for receiving wet fallout, provided with a first sensor able to emit a signal when a certain wet fallout sample volume has been collected; a closing device permitting the alternating closure of the two receivers as a function of a signal emitted by a precipitation detector; a measuring device located at the outlet of the second receiver and used for carrying out measurements of physicochemical quantities on the sample; a sampling device located at an outlet of the measuring device and used for arranging and keeping at a temperature below 0 DEG C. a fraction of each sample collected; and a checking system used for automatically controlling the aforementioned components as a function of the signals emitted by the sensors, including the first sensor and the precipitation detector and for managing the measurements performed on the sample.
