The body and funnel of the RG13 are made of durable aluminum alloy. The tipping mechanism consists of a divided bucket pivoted at its center. Rain collects in the upper half, and when full, it tilts to empty the collected water, allowing the other half of the bucket to begin filling. A siphon device ensures a constant flow rate into the tipping bucket for easier calibration and more accurate measurement.
