When And Why Did The Rain Gauge Came About?

Have you heard about rain gauges? Alternatively, perhaps you might have used it already and just do not know its history and the principles that serve as its foundation for being invented.

The rain gauge is a term that also applies for udometer, pluviometer or cup. Hydrologists and meteorologists usually utilize this instrument, as you may very well know already. They use it in order to gather liquid precipitation, manifested by the rain, and measure its total amount over a certain timeframe.

It was during 500 B.C. when rainfalls where known to be first recorded and kept. This was done by Ancient Greeks and was followed by the early inhabitants of India, after 100 years. According to studies, the people in India use bowls in order to catch the rain and record it. The rainfall readings where used to link with data or expected growth and even utilized as the basis for the computation of land taxes.

The state storehouses at Magadha were already equipped with the standard type of rain gauge in order that they can set precise standards as to grain production and classification of land for purposes of taxation.

Sources have also been known to state that Korea’s Cheugugi is the first ever rain gauge and still other sources declare that an existing gauge has already been developed or refined by Jang Yeong Sil of Korea.

Meanwhile, Christopher Wren in Britain first created the tipping bucket rain gauge type in 1662 AD

Most types of rain gauges records the amount of rain in millimeters. On the other hand, the rainfall level is sometimes reported in centimeters or inches. The data generated from a rain gauge can be read either manually or through an Automatic Weather station or AWS. Reading frequency depends on the demands of the specific agency that collects the readings. In some cases, precipitation data of a country’s area with sparse population would be obtained from a group of volunteers to supplement a weather observer who needs to be paid.

In order to get records on the pollutant levels that abound during a certain rainfall, some weather stations submit rainfall and even snowfall for specific testing.

A rain gauge has limitations and the data that can be read from it may be affected by several factors. Collecting data from a rain gauge during hurricanes, for example, is quite impossible to achieve. If ever the equipment survived the strong winds brought about by the storm and was able to collect a certain data, it could be rendered unreliable. Furthermore, rainfall data collected by a rain gauge is only applicable on a local area.

When the temperature is below freezing point already or even just close to it, the rain that fall into the rain gauge’s funnel could freeze, or the snow collected would not allow subsequent rain to go past it anymore.

Like many other instruments for meteorology, rain gauges must be placed far away from trees and buildings - factors that could affect the data it will be able to collect. As much as possible, it must be placed on a higher surface and not staked onto the ground, where its data might be compromised by water from other sources that could drip into it.

Are you interested to put up a rain gauge in order to know your lawn?s requirements in terms of moisture every week? Would you be interested to know the amount of water your lawn is getting from your sprinkler system? Well, you need not buy a rain gauge, especially if you lack the budget.

A simple rain gauge can be made out of several empty cans of tuna or similarly sized cans marked with one-inch level. Place this around the area where your sprinkler system will be applied and determine how long an interval it would take for the sprinklers to fill up 1 inch of the cans. This will help you determine how long you need to set your sprinklers on until the soil gets the ideal amount of moisture you require.

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.

The Benefits Of Using Wireless Rain Gauge

The wireless rain gauge is just another kind of rain gauge that provides the same benefits. But if you want a device that gives less fuss, the wireless type gives you a notched up version of the conventional rain gauge. As what the name asks for it, it functions without the wires. Unlike the conventional rain gauges, the wireless rain gauge lets you enjoy the readings that it collects while inside your home or office. This is done with the help of the digital display, which provides the actual readings of the rain fall amount collected from the outside.

The wireless rain gauge is perfect for individuals who do not want the hassles of going out to collect weather data, specifically the amount of rain fall. It lets the user collect the data without the hassles of the outdoors. But if you don’t mind going out in the sun or in the rain, a conventional rain gauge would suffice.

There are two parts comprising the wireless rain gauge:

a.) The actual gauge ? this is the device you mount outside and it does the collection of the rain water fall. The device can be mounted on any area of your outdoors, whether at the backyard, on a pole, on your deck, and any other fixtures you have.

b.) The wireless receiver ? this is your digital display put indoors. It is also called the weather station, and which that provides all the collected data by the actual gauge outside and lets you read it in the comfort of your home or office. The display can either be mounted hanging on the wall or can be on a free standing or the removable type.

Depending on the type of wireless rain gauge you have, its weather station may not only provide the amount of rainfall at a certain period of time. It can also collect other important and useful information like indoor temperature, outdoors temperature, and a lot other weather-concerned information. The accumulation of rainfall data can be done over a different set of time period such as hourly, daily, weekly, and even annually.

Range

It depends on the kind of wireless rain gauge you install, but most of them available in the market provides a range of between 100-330 feet. So, you can still enjoy the readings even if you have a large lawn background.

Battery

Most wireless rain gauges are also powered via solar, so basically, there is no need to use for any battery. However, like any other good wireless rain gauge, your device should come with spare batteries in case backup is needed.

Emptying rain water

This wireless device gives you lesser hassle after it accumulated the rain water. After the rain fall stops and with the help of the collection unit the rain gauge comes with, it will empty itself out with water that there is no more need for you to go outside to physically do the emptying task. Isn’t it way convenient than the other conventional rain gauge types you earlier used?

The accuracy of a wireless rain gauge can usually be tested by comparing its results over the findings of any local weather station in your location. You can also have fun comparing your findings with your friends and relatives. In many cases, you will be surprised how a wireless rain gauge can be accurate just like at the weather station.

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.

Have Your Own Homemade Rain Gauge

If you are creative enough and don’t like to spend extra dollar on a new replacement rain gauge to the recently broken one, why not start collecting your tools and equipment and make your own homemade rain gauge? It can be so much fun especially if you do it together with your kids or family. It can also be a great science project for students to learn more about weather ? specifically rain and its water cycle. Doing your own homemade rain gauge only requires minimal tools. Here are some guides on how you can start with this project.

Basic Overview of the Rain Gauge

The use of rain gauge, while may not interesting to many, can actually be useful especially because it allows us to learn and compare the rain fall trend from this season to another. It also allows us to know the weather even on those times when we were asleep. It affords us little excitement when there is a fore coming thunderstorm or heavy rain. And gives us compensation to minimal extent on those times when we know the disadvantages of wet days.

The general recommended practice of using the rain gauge is to examine it daily in a regular hour, say at every 8 in the morning and measure the collected rain water. Reports are made with the use of a dial or chart, where all the daily measurements of the collected water are entered.

The Standard Rain Gauge

Any standard rain gauge can be made with the use of cylindrical tube, with a diameter of 5 to 8 inches at the inner part of the rim and the bottom closed down by the use of a funnel. At the lower part of the cylinder, there is a glass catcher which stores the water delivered by the funnel until it is measured using the graduated glass. Good fit is ensured with the lower part so to minimize evaporation as much as possible.

What you need to make a homemade standard rain gauge

A homemade version of this device can be easily constructed with little expense. A cylindrical tin, brass tubing with a height of at least 3 inches and up, and a stout glass tubing with no more 1 quarter diameter with the receiver are the supplies you need for this gauge.

The Gauge

The cylindrical tin is used for your receiver. In this case, be sure to solder watertight the side joints and its bottom. If in case you use your tube for the gauge, solder the flat metal to one squared end. Next, place the receptacle on a level base, and then pour water in until reaching a mark 4 inches off the end of a wire positioned perpendicularly.

Corking the other end of the tube and pouring the water ? be careful not spilling any water ? this gives the number of your tube inches filled with the other 4 inches in your receiver. As you divide this result by 4, you have now your depth measure unit representing the inch of the rainfall.

The scale

To graduate your scale, use a smoothed white wood strip with an inch wide. Each inch, divide it into tenths, these tenths into hundredths, and so on until you have a scale that serves as the reading for the rain fall. Attaching permanently both scale and tube to a board will save you trouble and time as well as protect its tube from damage.

The receiver

This is your tin funnel, which serves as your receiver with a central hole made in its bottom and big enough to let the funnel pass through up the swell. The funnel’s rim is soldered to the receiver’s inside using little heat.

An Introduction To Rain Gauges

The term “gauge” may incur a myriad of meanings. There are several definitions that fit it. Hence, the meaning depends on its use. Generally, the name itself suggests an instrument that is used as a form of measurement. The features of the instrument refer to some quantity, dimension, and capacity for which it applies. It is in this light that a meaning is attached to the rain gauge.

What is the rain gauge?

The rain gauge is an instrument that is used to measure the amount of rainfall or precipitation over a particular period of time at a specific area. It is used as the ground for creating a precise reading in regard to the recorded data.

What is the use of the rain gauge?

The rain gauges are crucial instruments utilized in the study of the weather phenomenon. The meteorologists and hydrologists make use of these so that they will be able to examine and then gauge the exact level of precipitation or rainfall following a particular time frame. There are two major parts that compose the rain gauge. The first one is that wherein the rainfall or precipitation is collected. Meanwhile, the other is the one that measures the quantity of precipitation.

Furthermore, there are different forms of precipitation. It can be in the liquid form which is the rainwater or the solid forms which are the sleet, hail, or snow.

What are the varieties of rain gauges?

Again, these instruments come in different types. They are the weighing rain gauge, the standard rain gauge, and then the tipping bucket raining gauge. All of them present their own advantages and disadvantages yet they are one in terms of the goal of getting the best results. One more thing, these instruments must not be positioned in isolated or enclosed places such as near buildings, trees, tall objects, and other towering structures. If this happens, the results will be inaccurate.

The standard rain gauges refer to the graduated cylinders that come with the attached funnels. The graduated cylinder is positioned inside a bigger container that can accommodate any excess pouring. In this way, all of the rainwater gets collected.

Meanwhile, the weighing rain gauges feature the rotating drum, a pen, and some storage bin. It is the storage drum that collects any form of precipitation. The pen that is positioned below the drum records its weight.

The tipping bucket incorporates a large copper cylinder along with some levers, a funnel, and a recorder that is made up of a wheel and a pen. The levers are situated on an equilibrium which is like a scale. Whenever the explicit amount of precipitation has been reached, the lever then tips and sends the signal to the recorder. The pen moves either up or down as it records the lever movement together with the quantity of precipitation. Nowadays, a plastic container and a pivot comprise the modern tipping bucket rain gauges.

Why is the weighing rain gauge more advantageous than the tipping bucket?

The weighing rain gauge provides more accurate measurement in contrast with the tipping bucket. It is also capable of measuring the quantity or level of chemicals contained in the atmosphere. However, it can be quite costly and requires frequent maintenance.

Overall, whatever kind of rain gauge you prefer to use, what you should keep in mind is that it is able to achieve its purpose. That is, to gauge the amount of rainfall in your locale at a certain period of time.

All You Need To Know About Rain Gauges

Have you wondered about the amount of rain, snow or hail that reaches your home annually? Moreover, have you wondered how you can determine the amount of such weather phenomenon that reach the place where you live versus your relatives or friends’ place from another country, state or city?

Why bother, you might ask. Nevertheless, if you happen to ever wonder about this, then you might want to get yourself a rain gauge and have fun with determining the weather phenomenon that we call the rain.

A rain gauge is important to study of liquid precipitation, which is manifested in the form of rain. Hydrologist and even meteorologists in order to analyze and determine the amount of precipitation within a certain period often use this instrument. Rain gauges have two parts in order to determine both data. It comprises a part to catch the precipitation and another part to measure the total amount of precipitation caught.

A rain gauge can be effective when it is placed on an isolated area - ideally without trees and buildings since the presence of these structures could affect the overall data that can be generated by the equipment. Factors such as hurricanes and storms with terrible winds are factors that can also affect and influence the accuracy of data that can be generated by the rain gauge.

There are several types of rain gauges. Each type of this equipment has specific pros and cons whenever they are utilized. Here are the three types of rain gauge:

1. The standard rain gauge - this type utilizes a graduated cylinder with attached funnel, placed on an ideally bigger container. The container is for holding the excess that could pour out from the graduated cylinder.

2. The weighing rain gauge - for this type, 3 materials are used - pen, rotating drum and storage bin. The precipitation being monitored is filled into the storage drum. Meanwhile, the drum’s overall weight is recorded by the pen which is placed on the lower part of the storage bin.

The weighing rain gauge is capable of measuring the level or amount of chemicals that may be present in the atmosphere as the precipitation occurs. However, this type of rain gauge can be costly - making the instrument quite difficult to acquire. Still it is better than the tipping bucket rain gauge for it generates measurements that are far more accurate.

2. The tipping bucket rain gauge - this type uses several materials - big copper cylinder, funnel, two levers, pen and wheel for recording. The two levers are stabilized like a scale so that when a certain amount of the precipitation being measured is reached, it would tip over and signals the recorder. The pen makes upward or downward motions as it records the lever’s movement, along with the precipitation’s total amount. This type of rain gauge has been updated by utilizing a pivot and plastic container.

The rain gauge is not limited for use by hydrologists and meteorologist. News stations are also not the only ones with access to rain gauges. Anyone could buy a rain gauge to utilize for their own specific objectives.

Remember that achieving the purpose for acquiring such equipment is important, whatever type of rain gauge you choose to have. The objective of which is to have an accurate measurement of the precipitation amount on a given place and timeframe.

Decorative Rain Gauges For Your Home D?cor

Who said it that rain gauges have to be functional alone? With the decorative rain gauges available, fashion should never be left out by function. True, this device is used to measure the amount of rain fall on a particular day or at a set period of time. But while it is doing its own functional thing, wouldn’t it be nice if it appears so cute and fashionable with the rest of the surrounding too?

A decorative rain gauge will do those two things exactly as how you want it.

Take Your Pick: Typical Forms Of Rain Gauge

There are four typical forms of rain gauge. If you want to know more about these four forms in order to check out which type of rain gauge you would need, according to your specific purposes, then read on.

1.) The Graduated Cylinder or Standard Rain Gauge - this type was developed as the dawn of the 20th century approaches. It consists of a graduated cylinder with a funnel attached to it, placed in a larger container. The container contains the water that could overflow from the graduated cylinder. In measuring its results, the graduated cylinder is measured and the excess water that overflowed will be placed onto another graduated cylinder and measured again.

The usual measurement in the cylinder is millimeters and each of the horizontal line in it can be 0.2 mm or 0.007 inch. The usual measure of a graduated cylinder is only up to 25 mm or .098 inch. Anything over 25 mm will then flow over onto the small hole on the graduated cylinder’s top. This rain gauge utilizes a metal pipe attached to the larger container for adjustment purposes, just to make sure that it is level. Then, a metal rod placed on the ground will be fit over the pipe.

2.) Weighing Precipitation Gauge - A storage bin comprises this type of gauge. This bin is used to record the rainfall mass by weighing it. Some models of this gauge makes use of pen and rotating drum in order to get the mass, while in some models, a data logger is utilized which is attached to the bin through a vibrating wire.

This rain gauge type is usually more advantageous than the other type of rain gauge, commonly known as tipping bucket. It can measure other precipitation forms, such as the solid form of hail, sleet and snow and does not erroneously underestimate an intense or heavy rain. However, while it could generate far more accurate data, it is also quite expensive and needs maintenance more than the tipping bucket gauge.

Aside from measuring the total amount of rain on a given area for a specific period, the weighing rain gauge also has the ability to generate how much chemicals are present in the given area’s atmosphere. Scientists who study how the release of greenhouse gasses into the atmosphere can affect acid rain levels would find the data generated from this, very helpful.

3.) Tipping Bucket Rain Gauge - this makes use of big copper cylinder that is staked on the ground. A funnel is placed on top of this cylinder in order to collect the rain and channel it.

Then, the precipitation caught will fall into a small bucket placed on a lever, like a scale or seesaw. Whenever the precipitation amounts become equal to 0.2 mm or 0.007 inches, the lever will tip upward and it will send down to the recorder. A pen that is supported by an arm attached on a geared wheel serves as the recorder. The geared wheel will move once every time the lever sends a signal and every time it moves, the pen arm would either go on an upward or downward motion and leaves a recording manifested on a graph.

As previously noted, this type of rain gauge is not very accurate because sometimes, the rainfall has already stopped even before the lever was tipped and the next rainfall may not take more in order to tip the lever.

However, it is advantageous because through its records one can determine if the rainfall has been light, moderate or heavy. Nowadays, the modern type of rain gauge already comprises of a plastic rain collector, which is balanced on a pivot. Then, it activates a switch whenever it tips consequently recorded electronically or transmitted onto a remote station.

4.) Optical rain gauge - this type is comprised of a collection funnel set in a row. Below each of the funnels is a covered space with laser diode and phototransistor detector.

Rain Gauge ? History And Underlying Principles

Do you know much about rain gauges? Read on to find out the principles that comprise them.

Rain gauges are the instruments used to collect rain and interpret the amount of precipitation in a certain time period. Meteorologists and hydrologists make use of these instruments to come up with their recorded data.

Remembering its History

You must be wondering as to where the rain gauge originated and who were the very first people thought of using it. For the record, the very first rainfall records were safeguarded by no other than the Ancient Greeks. The date goes back to 500 B.C. After a hundred of years or so, the Indians thought of using ordinary bowls to collect and record the rainfall.

Their readings were then associated to the expected growth and later on to the quotations of the land taxes. Certain places like Magadha and Arthashastra based their grain production to the rainfall records. All of the state storehouses then adopted the use of the standardized rain gauge to be able to categorize the lands for the purpose of computing the taxes.

As for the first rain gauge produced, some records state that the Cheugugi of Korea was the first in the world while others point out that it was Jang Yeong Sil who developed it or improved the existing rain gauge during the time. However, it was Christopher Wren from Britain who made the first ever tipping bucket rain gauge in the year 1662 AD.

Getting to Know the Associated Principles

Generally, many of the rain gauges created measure precipitation via millimeters. The level of rainfall is also oftentimes recorded and reported as centimeters or inches.

The amount of rainfall gathered by the instrument can be read either manually or by employing the services of the AWS or Automatic Weather Station. The frequency in the readings highly depends on the requirements of the agency that is in charged of the collection. Other countries actually supply the paid weather observer with a bunch of volunteers who can take the precipitation data and some other changes in the weather. This is basically done for the benefit of those sparsely populated regions.

In some instances, the precipitation is never maintained. There are, however, other reading stations which do submit the rainfall records for testing purposes. This is mostly done to gain the levels of pollutants.

The Limitations and Usual Problems Encountered

This instrument likewise has its own limitations. When there is a hurricane, the collection of rain data is almost impossible. More so, the results can also be unreliable even when the equipment actually survives the danger. The extreme winds make things very impossible to execute.

The rain gauge can only signify the rainfall in a specific area. Some of the raindrops tend to stick to the funnel or to the sides of the device. Hence, the amounts can be underestimated.

One more problem that meteorologists and hydrologists face is the temperature that is almost close to freezing. The rain may fall on the funnel and the snow or freeze can be accumulated in the device. This then blocks the rain passage.

Overall, it is advisable that the rain gauges be put in areas which are far from trees and other structures to ensure that no factors will hinder the clear and precise collection and data reading.
