Filling of one bucket occurs at one-hundredth of an inch. The receiving funnel leads to one of two small buckets. The operation of a tipping bucket rain gauge is quite different from the standard gauge. Amounts that exceed the tube capacity are caught in the outer shell of the gauge, allowing the recorder to pour out the liquid in the tube and fill it back up if needed. Magnifying the rain in this way allows precise measurements down to a one-hundredth of an inch. The area of the collector is 10 times that of the tube thus, the rain gauge works by magnifying the liquid by a factor of 10. These gauges work by catching the falling rain in a funnel-shaped collector that is attached to a measuring tube. The recording of rainfall using the standard or funnel rain gauge is generally done manually. Let’s take a closer look at these types of rain gauges and how they work. Further distinguishing aspects such as how they are set up and how they deliver data can be made, though the basic operation of rain gauges does not usually vary from these primary rain gauge types. The three major types of rain gauges are the standard gauge, tipping bucket gauge and weighing gauge. Measuring rainfall can be is primarily done in three different ways using three different types of rain gauges.
