Rain Gauge: What Does It Do

Your area may experience more rain than other locations where your family or friends live. If it is the case, it is probably normal routine for you to constantly encountering wet days and has never considered it as a hassle.

But if you can’t get yourself getting used to the soaked experience of the rain, or it is not much fun not knowing when the rain would be heavy or light, you probably need a gadget that helps you tell how much water would drench your location. A rain gauge would be the perfect device you need at this specific application.

No, you don’t have to worry as rain gauge can be purchased anytime by any ordinary individual like you. Though it is a weather instrument that is used for professional needs, basically by hydrologists, meteorologists, or other experts of any news or weather station, it is not available alone for such professional application.

For amateur levels, rain gauge can be purchased just about anywhere. It can be bought from specialty stores and – and even online. That is how much accessible this device already is to provide convenience to the questioning individuals who are concerned of how much amount of rain will continue to exist in a particular location.

What Does It Do?

Basically, the rain gauge is used to measure the liquid or its precipitation at a particular set of time. It is a simple yet very useful instrument not only to the weather makers but to the gardeners, harvesters, farmers, and other common folks.

It is typically made of three different parts, the cylindrical tube, outer container housing the tube, and the funnel placed atop the cylinder and the container.

When the rain falls, the liquid goes in through the funnel on the top. The liquid is collected into the cylindrical tube, which is marked with measurement lines in millimeters.

If the water collected in the cylinder overflows, the liquid will continue to the outer container. The final measurement of the rain water will be recorded after a set of time is finished. The overflowed water which was collected in the outer container will be emptied into another cylinder.

Adding both waters from both cylinders will give the final number of the rainfall. It depends on your location but the measurements can be converted into centimeters or inches if there is a lot of rainfall.

Basically, that is how rain gauge functions. But there are different rain gauge types available out there, including the wireless ones, so they may employ different methods. Others are a little more high-tech while some functions basic. However, they all work to accomplish similar goal.

Ideally, the rain gauge must be mounted on an elevated place or above the ground, say on a pole or rooftop. However, if the device is to be placed on the ground, it should be on any open area where no other objects like trees or plants potentially hindering the accuracy of the rain gauge.

Conclusion

The advent of the rain gauge is such a genius help to all individuals who need information which otherwise wouldn’t be easily acquired with the absence of the said device. The rain gauge may be a small, simple device yet the thing that it can do creates a big change not only to the weather makers but to other sectors as well.

An Overview Of The Tipping Bucket Rain Gauge

Sure enough, there are various types of rain gauges. One of which is the tipping bucket rain gauge. Read more for further information about this instrument.

The Concept Explained

The rain gauge is basically the instrument that is used to collect and then measure the quantity of liquid precipitation over a certain time frame. It is different from the one used to measure the solid precipitation which is known as the snow gauge. The rain collection instrument is therefore utilized by the hydrologists and meteorologists so they can better have a more precise data in regard to the amount of rainfall in a localized area. More so, it also goes by the names pluviometer, cup, or udometer.

Nevertheless, the tipping bucket is the kind of rain gauge or meteorological device which measures the quantity of rain or precipitation that has fallen. It is a measuring device that is used to gauge rainfall.

Getting to Know How it Works

There are several parts that comprise the tipping bucket rain gauge. These parts allow the possibility of coming up with an accurate measure of the rainfall. When the rain falls, the funnel that composes the instrument catches it. The water then travels down towards the funnel and then drips into one of those thoroughly attached “buckets” that balance on a pivot. You can imagine a see-saw thing here.

The bucket placed on top is supported by a magnet until such time that it gets filled up to the specified amount. That is, about 0.001 inches of rain water. As soon as this amount is met, the magnet automatically releases its hold thereby making the bucket tip. The water then goes down to the drainage hole. While this process goes on, the other bucket is raised to position under the funnel. It is when the bucket tips that the reed switch or sensor sends the message to the weather station.

The display or weather station bases the readings on how frequent the switch is turned on. The display then estimates the rainfall by using the units of measurement like inches or millimeter.

A Discussion of its Advantages

The tipping bucket can determine the characteristics of the rain as to whether it is light, or medium, or heavy.

The quality of the rain is easily specified by means of determining the overall amount of rain which has fallen at a certain period of time. The period is normally for about an hour. A 10-minute counting of the number of the clicking allows the observer to tell the characteristic of the rainfall.

Some Disadvantages Revealed

The tipping bucket rain gauge is oftentimes doubted when it comes to the readings that it provides. For one, it is not guaranteed that an accurate data will be revealed in contrast to what a standard instrument does. The reason for which is because the rainfall may already stop even before the lever tips. Over the next few rounds of rainfall, it may actually take more than one drop of rain to get the lever to tip over. Hence, the measurement can read as 0.2 mm when in fact only a few droplets have fallen.

Another disadvantage of this type of rain gauge is that this instrument may underestimate the quantity of rainfall especially during the heavy rains or extreme snowfall.

Rain Gauge ? Its Types And Standards

What is a rain gauge? What is its use? Who uses it? Perhaps you have heard of it a hundred times already. Hence, for someone like you who doesn’t know much about what this instrument is for but it is clear that you are after the helpful bunches of data about it, then, you just found the perfect article that will suffice your queries.

The Types of Rain Gauges

Among the popular and commonly used types of rain gauges are the weighing gauges, graduated cylinders, simple buried pit collectors, and the tipping bucket gauges. They all have their own share of pros and cons in line with the collection of rain data.

A Look at the Standard Rain Gauge

The standard type of this instrument was developed at approximately the beginning of the 20th century. It particularly consisted of a funnel that was attached to a graduated cylinder that suited into a bigger container. Almost all modern rain gauges are patterned to this early model.

Moreover, the design allows the outside container to catch the water that overflows from the smaller-sized graduated cylinder. As it is measured, the water that is collected in the graduated cylinder will be gauged. The excess rain water will be placed in a different cylinder and will be measured as well.

Typically, the cylinder uses the millimeter unit of measurement. The bigger container is the one that is used to gather the rainfall that amounts to more than 25mm which flows out from the tiny hole located on top of the smaller cylinder. There is a metal pipe which is affixed to the container that is flexible and adjustable to guarantee that the rain gauge is showing the appropriate level. The pipe is then fitted over some kind of a metal rod which has been originally affixed in the ground.

The Weighing Precipitation Gauge

The weighing type precipitation gauge is made up of a storage bin that is used to record the mass. There are models which gauge the mass with the use of a rotating drum or pen or by means of a vibrating wire that is connected to a data logger. Its primary advantage is that it rarely underestimates the extreme rain and it can still gauge other kinds of precipitation like snow, hail, and rain. However, they are more costly and needs higher maintenance level.

Likewise, this type bears a kind of device that promotes the measurement of the amount of chemicals that are contained in the atmosphere of a particular location. Scientists who study the greenhouse gas effects as well as their effects on the acid rain levels find it very helpful.

The Tipping Bucket Rain Gauge

This type is composed of a big copper cylinder which is normally secured to the ground. At the top is the funnel which responsibly gathers and then channels the precipitation. The latter then falls into one of either the levers or small buckets that are balanced like the scale. When there is about 0.2 mm precipitation amount, the lever tips fall and then an electrical signal is transmitted to the recorder.

There are of course several modern models being used these days. Their designs may vary but what remains alike is the purpose that they serve. Professionals also have their own methods of reading the data and providing accurate records.

Measuring The Weather With Rain Gauge And The Others

You must have heard about the rain gauge, wind gauge, and many others while you were studying in your old school a few years back. Well, they are the weather instruments. But how can they measure the weather?

As you watch the news channel, your weather forecaster provides you with the detailed information about the condition of the weather for the day or for the entire week. Although you may argue that the weather remains unpredictable, your weathermen simply makes a forecast. Meaning to say, they base their details on the use of some instruments which supply them with the accurate readings. Yes, they try their very best to come up with the best results. That is, to measure everything in a precise way. However, there are some factors that hinder them to get the most exact readings such as hurricanes, snow, and storms, to name a few. Through all of these, it piques a particular interest on each and every one of us as to how the weather professionals study and measure the weather.

For the record, there are five main instruments that are used to get the accurate readings of the weather. They are the rain gauge, the anemometer or wind gauge, barometer, weathervane, and the thermometer. How do they differ in nature and function? Read on below.

The rain gauge. This device comes available in a variety of sizes and shapes. You can see one that looks like a glass jar or something that is shaped like a butterfly, a dog, or a frog. From the conventional design with the graduated cylinder and funnel, technological innovations have paved the way for more styles, sizes, and shapes. There are also different kinds of this measuring instrument like the tipping bucket, the standard rain gauge, or the weighing rain gauge.

Anyhow, they all bear the measuring lines on the side which can either be in millimeters or inches, depending on the amount of rainfall that a particular location gets. A new addition to its family is the wireless rain gauge which can be mounted anywhere in the lawn. It electronically transmits the data so you can do the reading even when you are indoors. There is also another kind which has the self-emptying feature so you can conveniently measure the level of precipitation despite the heavy downpour.

The anemometer. Also known as the wind gauge, this device measures the speed of the wind. Its conventional form is the cup-anemometer which bears four hemispherical shafts which are positioned horizontally towards one another. There are two categories of anemometers. One is the fixed wind gauge which is used to measure the speed of the wind in a particular location. It is capable of giving out other details like the maximum and average wind speed. The other group is the hand-held anemometer which simply displays the momentary wind strength. It is portable and can be taken anywhere.

The thermometer. It measures the temperature. From the conventional mercury thermometer, here comes the wireless thermometer which can either display the temperature in Celsius or Fahrenheit.

The barometer. This is a useful instrument for making weather forecasts since it gauges the atmospheric pressure. It indicates whether the pressure rises, falls, or remains steady.

The weathervane. This device tells the direction from where the wind is blowing.

Now it’s clear as to how the weathermen analyze, measure, and forecast the weather phenomenon. That is by means of using all these basic instruments.

Rain Gauges ? The Decorative And The Wireless

Over the years, weather professionals, novices and just plain weather enthusiasts have been using rain gauges, which deliver its main purpose and provide other bonus features. They now have the decorative and the wireless rain gauges.

So what is a decorative rain gauge aside from the fact that it is decorative?

Well, decorative rain gauges are interesting and comforting sights on the front lawn or backyard of a house during days when rains or storms abound. It does perform its primary function and purpose, which is to determine the amount of rainfall or other types of precipitation that your area had by millimeters or inches. In addition, all the while it delivers the results, it would bring an added look of charm on a garden, backyard or front lawn.

Nowadays, having a decorative rain gauge can surely accentuate a backyard, patio, deck, porch, and lawn grounds. It could be a very decorative but also a very functional mechanism. However, if preferred, it can also be just a decorative fixture on the living room or bedroom, without having to use it functionally.

Since they are decorative rain gauges, they can be shaped to become anything that would truly add accents to the overall landscape. They can be shaped as a frog, dog, bird, flower, fairy or even a garden gnome if preferred. Now gardeners may really delight in the concept of having a rain gauge put up without having to make sure that it does not mess with the overall image of the garden. They can have interesting accents and still help them know the amount of precipitation in their area, how great can such equipment get?

A decorative rain gauge can be either staked in the garden grounds or mounted on a pole or railing, depending on how it would affect the general view of a backyard, porch, lawn, deck or patio. Still, if the main objective of putting up the rain gauge is to get accurate data on the amount of precipitation and not just as an added attraction, then rigging it up on a higher surface is recommended. This way, the only thing that would fall into it will be rain and nothing else.

Having the rain gauge on the ground might contaminate the data it will generate because of factors like drops of water that could drop on it from nearby trees or plants. Wherever it may be put up however, one thing is sure. Decorative rain gauges can really add a trendy look to your outdoor or indoor home facade.

On the other hand, there are those who prefer having rain gauges without a lot of fuss. That is why they opt to have the wireless rain gauge. A wireless rain gauge serves its main purpose without the inconvenience in retrieving the data it generates. It has two main parts: the actual rain gauge, which is placed outdoors to catch the precipitation and a weather station or wireless receiver to indicate its readings. With this wireless receiver, the owner need not come out to get the gauge’s reading and just take it from the comfort of indoors.

The wireless receiver would have a digital display that will report the amount of precipitation that is going on in the area, in millimeters. It can also give out other data such as the outdoor and indoor temperatures, cumulative rainfall to be expected for a specific period – per day, week or year, etc.

Wireless rain gauges that are usually offered in the market have a range of 100 ? 330 foot. Moreover, there are those that are already self-emptying. Totally fuss-free, the owner need not empty out the gauge physically after the rain.

So, for those who opt to send out rain gauges as gifts for their friends or family, what is it to be ? the decorative type or the wireless type?
