ABSTRACT:
According to the present invention, a raingauge which is fully automatic and free of any mechanical moving parts, comprising a receiver for collecting rain water, a water transfer device designed to transfer the water received by the collector to the discharge orifice in such a way as to isolate the discharge orifice from the effects of pressure fluctuations due to wind, the momentum of the rainfall, and the impurities that may be in the rain, and a discharge orifice which is designed to discharge an equal volume of water from the device by utilizing the surface tension characteristics of water, the restriction in the discharge orifice, and the force of gravity. The net effect then, of these three forces or characteristics acting upon the water accumulating in the funnel orifice combination, being that the water will discharge in the form of a droplet and be in equal and consistent volumes. Further, the raingauge comprises an electrical probe matrix designed to sense the discharge of an equal volume of water, and an electronic counter circuit that communicates with said probe matrix by utilizing extremely low current signals, yet without the need for a signal amplifier. Said electronic counter than converts the signals from the probe matrix into a display representing the rainfall amount.
