5.1 Rain Gauge

An external “tipping bucket” rain gauge (Cat. No. 2149) can be connected to the Rain Gauge connector of the sampler (Figure 21). The rain gauge provides a dry contact closure to the sampler.

As rainfall collects in the 20 cm (8 in.) diameter funnel, it is directed into one side of a “tipping bucket” assembly. As each bucket fills, it causes the bucket assembly to tip and empty out into the bottom of the rain gauge. Each tip of the bucket causes a single contact closure to the rain gauge and sends a short 12 V dc pulse into pin C of the Rain Gauge connector. Each pulse (tip) represents 0.025 cm (0.01 in.) of rain.
