What is a rain gauge used for?
A rain gauge (also known as an udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined area, period of time.
How a rain gauge is used to measure rainfall?
Instruments. The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.
What do you need to know about a rain gauge?

What kind of instrument is used to measure rain?
A rain gauge (also known as an udometer, pluviometer, or an ombrometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a set period of time.
Why is the measuring tube removed from a rain gage?
Both the collector funnel and the measuring tube are removed to allow snowfall to collect directly in the overflow can. Obviously, if the funnel were left in place, snow would quickly accumulate and mound it over. Also, freezing rain would quickly plug the small orifice of the funnel.
How does a tipping bucket rain gauge work?
The rain gauge performs its function by magnifying the rain by a factor of 10. Magnification of rain helps in attaining accurate measurements. Working of Tipping Bucket Rain Gauge: The operation of a tipping bucket rain gauge is completely different from the standard rain gauge.
