Answer:
rain gauge :-
a device for collecting and measuring the amount of rain which falls.
A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area.The rain gauge is composed of three parts: a funnel, a measuring tube, and a 4-inch diameter overflow tube, and a mounting bracket. The funnel directs the precipitation into the measuring tube and magnifies it by a factor of 10.A rain gauge is an important tool to help monitor global weather patterns, aid farmers dealing with drought and help meteorologists prepare for natural disasters.Rainfall is extremely variable, both over time and between different locations, which makes it very difficult to measure. A rain gauge basically collects water falling on it and records the change over time in the rainfall depth, which is usually expressed in mm.Place the display unit close by so you can monitor it during the calibration process. Make a pinhole in the bottom of a plastic cup. Hold the cup over the rain gauge and fill it with exactly 1 cup (8 oz.) of water, allowing the water to slowly drip into the rain gauge.
hope it helps you
