The paper presents description of the optical rain gauge, virtual measuring area, and criteria of the measuring area defining. The probability calculation for simultaneous registration of multiple precipitation particles is performed. It is shown that the developed device should provide simultaneous recording of two raindrops at least. Estimations of the transmitted data traffic and calculation of the instrument sensitivity have been made. It was concluded that this gauge has wider possibilities and related prospects in comparison with traditional rain gauges.
