How to Use a Rain Gauge
The rain gauge is a device that records precipitation in a standardized way. It collects rain water in a bucket supported by a spring balance. When it rains, the lever arm of the balance touches a drum mounted on a clock. The pen of the balance then writes the amount of water on a graph paper. A recording can be made every 24 hours or every seven days depending on the model. To get a reliable reading, a rain gauge should be situated in an open grove of trees.
In a sheltered area, it is recommended that you place the rain gauge on level ground. Make sure that there are no obstacles in the way of the gauge. Avoid placing the gauge under any tree or other structure that may interfere with its operation. Also, avoid installing the rain gage near any building, as this will cause the rainfall to be overstated. You should also keep in mind that a raingauge requires careful maintenance, especially during periods of dry weather.
To maintain the rain gauge, ensure that it is installed in a sheltered location. It is important to place it at a level surface because excessive rain will splash onto it. A higher rim will also cause rain to be blown away and will not account for the rainfall. Usually, the rims of the rain gauge should be at least 300mm off the ground. Short grass and gravel will prevent splashing. If you are using a rain gauge on a terrace, consider putting it in an open area with low grass or gravel.
A rain gauge can be a good investment if you live in a tropical region. The tip of the bucket empties once five millimeters of rain are collected. The measuring glass has an accuracy of 0.001mm. When the tip of the bucket empties, the device automatically triggers an autographic recorder to record the tilts and record the data. The results are reported as the daily rainfall in the area. To make the most of the rain gauge, you must maintain the device during dry and wet weather.
The rain gauge is a great investment. During a storm, the tip of the bucket will fill with water when it collects five millimeters of rain. It will also fill with water after 0.2mm is collected. The data is stored in a computer and can be used to quantify rainfall levels. However, it is important to note that the rain gauge should be used regularly. It should also be refilled with water if it is filled.
Rain gauges have many uses. They can be used to measure rainfall, but they can also be useful in determining temperature and humidity. You should choose a rain gauge according to the type of weather you’re experiencing. If it’s too cold to use, you should place it somewhere that is above freezing. During wet weather, the gauge should be in a shaded area. Leafy trees can also obstruct the readings.
