Davis rain gauge
Description
The Davis Rain Collector II is a typical example of a tipping bucket rain gauge with
a 2-wire connection. This information can be applied to any pulse output style rain
gauge.
Electrical connection
• The gauge is connected to an input of the C3 via the pre-wired 10 m cable
supplied with the rain gauge
• The cable from the gauge has four wires, only two are required
• Any of the four inputs to the C3 may be used (Figure 31)
Installation notes
• The gauge must be mounted on a level surface and be positioned such
that there are obstacles ‘shadow’ the gauge from rainfall
• The gauge must be cleaned periodically to prevent the inlet becoming
blocked
