A rain gauge is a device that a hydrologist or meteorologist would use to measure precipitation. They measure the certain amount of time it takes for sleet, hail, rain or snow to precipitate.
Rain gauges usually measure in millimeters providing them with the amount of rainfall. Some are already calibrated to be able to read the amount of rainfall directly. Other gauges are calculated by the depth of water in the container collected through a funnel.
A polyester or copper funnel make it easy to collect rainfall in an enclosed cylinder. On an automatic rain gauge, there is a recording chart that is mounted on a drum.
Rain gauges are essential for those who farm and raise crops. Farmers need exact data in their area calculating the amount of rainfall. This helps famers better forecast their harvest time and yield.
Having your own rain gauge allows you to get exact results without having to rely on the news reports. These are simple instruments that can give you results in inches or millimeters. Smarter decisions can then be made when it comes to caring for your land and crops.
Different plants grow in different climates therefore, it’s important to use your rain gauge to know which will thrive. A rain gauge will provide you with the best results you couldn’t find anywhere else.
It is important to select the proper rain gauge. Due to changes in rainfall, the gauge needs to be able to measure a wide variety of intense conditions. Your gauge will need to be able to measure from light rain to a heavy downfall.
Many low cost gauges are not as accurate as the higher end devices. A manual rain gauge is a vertical tube that has a millimeter or inch scale shown on the tube. The manual gauge measure rain daily and then emptied.
If you are experiencing heavy rain, some manuals contain an overflow tube that is essential for accuracy. They can provide accurate readings to 1/100th of an inch. These are the most popular rain gauges used.
Weighing rain gauges collect rainfall via a container that is on a scale. These are ideal for heavier rainfall and are weighed periodically. This is a great gauge to use when measuring snow, sleet and hail.
You may find that weighing gauges are more expensive however, they are one of the most accurate gauges on the market. A tipping bucket rain gauge comes in a wide variety of price and quality. They are also the most popular.
They are two buckets that attach side by side and sit on a pivot. A funnel is then used to direct rain into its container. Once the container becomes full, the bucket tips and empties the rain into the other bucket. This type of rain gauge is less accurate then its counterparts.
The bucket may remain only partially full at the end of rainfall. This causes it to only tip when a new rainfall period begins. Most models under record high downpours of rain. Acoustic gauges measure rainfall by counting the specific number of drops.
The rain drops fall onto a plate located above a sensor. Many people prefer these types of gauges because they can differentiate between rain and hail by the acoustic signal it generates. They can tend to report rainfall inaccurately but they are maintenance free.
With acoustic gauges, if you are experiencing heavy rain it becomes harder for the device to count each drop. Once the sensor becomes saturated the signal levels off. With the tipping bucket rain gauge, the water will spill over if both are full.
If you live in a climate that has high rain intensity, the accuracy of your readings will be incorrect. It is very important to choose a rain gauge depending on how long you want it to last. The answer depends on where you plan to put it.
The type of rain gauge matters if you life in a dry climate with very few showers. It also makes a difference if you live in tropical areas or near the ocean. If you purchase a cheap gauge and live near the ocean, you are guaranteeing it will not last longer then a year.
Corrosion easily happens in this type of environment and a cheaper device will not be able to withstand such conditions. An acoustic style gauge is more ideal for harsh climates.
