U.S. standard rain gauge Optical rain gauges were developed in the late 1990s and are relatively expensive. The movement of bucket due to its increasing weight is transmitted to a pen which traces record or some marking on a clock driven chart. The most common types, according to their principle of operation, are 1) tipping-bucket rain gauge , 2) weighing rain gauge , 3) capacitance rain gauge , and 4) optical rain gauge . Its movement being recorded by a pen moving on a recording drum actuated by a clock work. If the water overflows from the graduated cylinder the outside container will catch it. This rain gauge is adopted as the standard recording rain gauge in India and the curve drawn using this data is known as mass curve of rain fall. float-type rain gauge. 34.
