Usually, a rain gauge is a container with a tapering funnel with standard dimensions. The container is placed on the ground. The rim should be set about 30 cm above the ground’s surface. Some gauges can read the rain directly, while others must calculate the rainfall based on the depth of the water. Whichever type you choose, make sure it works for you. The most common types of rain gauges are available for purchase online.

For accurate rainfall measurements, the location of a rain gauge is critical. The ideal exposure eliminates turbulence or eddy currents near the gauge. It reduces the amount of catch, particularly during increased wind speed. Placement in an open grove of trees is ideal. The height of the projection from the gauge should not exceed one metre. However, there are other factors to consider. Read this article if you are concerned about placing a rain gauge in an exposed location.

First, you must consider where to mount the gauge. If you mount it on a fence post, place it at least 5 feet off the ground. A higher height will allow for better catch and reduce the impact of nearby objects. If the gauge is placed on a post, place it at an angle to minimize rain splashes. The highest-quality gauges have a post at least 20 inches off the ground.

Next, you must decide where to place your rain gauge. You should avoid placing it too close to high-traffic areas, buildings, and trees. Also, ensure the rain gauge is level to avoid splashing out or blowing into it. In addition, you must carefully observe the measurements made by the rain gauge to ensure that it is accurate. Further, you should use a rain gauge that is easy to use and does not require additional skills.

In collecting accurate rainfall data, it is important to install a rain gauge from near the site under investigation. Using rain gauge data can help you interpret hydrographs by providing data on precipitation intensity. Additionally, they provide valuable information on shallow groundwater quality. They can also aid in the construction of hydrographs. With this information, you can make a more accurate assessment of groundwater quality near the site.


A rain gauge is a type of weather station that measures rainfall. It works on a seesaw model, wherein a collection bucket rests on a weighing platform. As rain falls, the seesaw will jump, and the electronic recorder records the weight of each beat. This data is recorded on a computer, which forms a rainfall graph. Generally, rain gauges are placed at a certain height from the ground and can record rainfall for 12 hours.

There are two types of rain gauge. One uses a siphon mechanism to collect the rainwater. The rainwater is collected in a rectangular container with a float at the bottom. A pen that moves on a recording drum actuates the siphon. Once the float reaches the top, the siphon releases the rainwater. It allows the collector to see how much rain fell in a particular area. Rain gauges are useful in monitoring rainfall patterns and helping meteorologists identify the heaviest rain.

Another type of rain gauge is a tipping bucket model—this device channels rainfall into a small container. When the float reaches its top, it will rise, meaning significant rain. An electric current will run through the float and send an electrical signal to a computer. An older rain gauge may contain a recording device consisting of a pen mounted on the arm attached to a geared wheel. The pen arm will move as the wheel turns, leaving a trace on a graph and creating a distinctive “click” sound.

The standard rain gauge is designed to have an overflow can that collects water when rainfall exceeds 2.00 inches. It can hold up to 20 inches of water, and it also serves as the primary collector in frozen precipitation events. However, it is recommended that the collector funnel be removed when solid precipitation is expected so that snowfall will fall directly into the overflow can. However, freezing rain can clog the small orifice, making rainwater measurements difficult.


Once you’ve decided on a measuring method, it’s time to start collecting your rain. You’ll need masking tape, plastic bottles, and an accurate rain gauge to make your rain gauge. Markings of quarter inches or so are especially helpful on glass jars, but plastic bottles with ridges are easier to draw on. Once you’ve collected a few days’ worths of rain, you’ll be able to compare the amount of rain to previous days.
