How a Rain Gauge Works - Simple Diagram & Explanation #3039866 (License: Personal Use)

This schematic shows a classic cylindrical rain gauge with a wide funnel at the top to capture raindrops, directing them into a narrow measuring device calibrated in milliliters or inches. Excess water flows into an outer overflow cylinder to prevent spillage during heavy downpours. The design ensures accurate measurement while accommodating varying intensities of precipitation.
