If you are buying and using a rain gauge for the first time, then you should learn all the basics about the instrument. It is not a complicated device or apparatus to use. But the reality is that you’ll never obtain accurate rainfall measurements if you do not know what you’re doing.
This article will help you go through the process of buying and using a rain gauge Australia without any hiccups.
Concentrate on the Size
If you are uncertain about the capacity, you should select the big one. It may cost you a little bit more, but the extra costs are needed if you want to attain maximum precision. In addition to having the primary collection location of 200 cm2, the larger size has some other benefits over its little sibling, such as much better resistance to heavy rains and less evaporation.
There are numerous variations of the rain gauge out there and selecting the right one can be difficult. They are typically made from stainless steel, aluminium and polycarbonate. All of them are great, but the latter is essentially impervious to severe temperature levels, bumps and falls. Also, some rain gauges are more resistant to UV radiation and help to prevent evaporation. Lastly, ensure that the cylinder you are purchasing has a resolution of a minimum of 0.1 mm.
Environment or Setting
The wind is the main hindrance to reliable rain data, so prevent positioning your rain gauge Australia in a windy location such as the top of a building. Experts agree that the perfect area for a rain gauge would be a little open meadow surrounded by forest. Likewise, remember that any hindrance near your rain gauge like trees will obstruct rainfall from reaching the gauge. The obstruction may also trigger rainfall to splash towards it, therefore impacting your measurements. The guideline is that the distance from your rain gauge to a barrier cannot be less than two times the height of that challenge.
4– Installing Height
The rim of your rain gauge must be positioned at 1.5 meters in the air. It’s likewise extremely crucial to utilise a bubble level. Its purpose is to make sure the gauge is put in an entirely flat position so that it can gather all the rainfall.
Regular cleaning of your rain gauge is necessary to guarantee optimum precision. You begin by removing any leaves or debris that might be blocking the funnel. When done, you can clean the inner cylinder by twisting a thin, soft towel and spinning it into the cylinder up until it reaches the bottom. Furthermore, you can put some warm water with a little liquid hand soap into the cylinder and after that clean it up using a washcloth or anything like it.
