Rain Gauge

To measure rainfall at ground, we use several measuring devices based on two different measuring principles. On the one hand, the measurement is done by means of a tipping bucket, which works well only if there is sufficient rainfall. In case of low precipitation, it may happen that the small amount does not cause a tip. The resolution of this principle is roughly at 0.1 mm. An alternative measuring principle is to use a drip device, producing drops of constant and known size. Counting the drops by a light-barrier provides directly the rain intensity. For weak and moderate precipitation, the second principle is more precise. In heavy precipitation, it suffers from an unstable drop sizes, and in worst case, individual drops are no longer distinguishable.
