This self-emptying, tipping bucket style rain collector utilizes an 8″ diameter opening to meet NWS specifications for statistical accuracy. Rainfall is gathered in the collecting bucket and funnels through a small opening into a tipping mechanism. When the mechanism has 1/100th of an inch of water in it, it tips. A count is then transmitted to an indicator and the water empties from the tipping mechanism, through the bottom of the collector bucket to the outside.

The rainfall collector weather instrument requires no manual emptying. Each tip of the bucket is equivalent to 1/100th of an inch of rain. It utilizes a normally open circuit that is momentarily closed each time it tips. As such, it can be connected to any simple counting circuit, including Maximum’s Rainwatch indicator.
