Criteria Used for Evaluation

Size

Size

While some people buy a rain gauge for the sole purpose of measuring rainfall, others look at other added benefits or features that will be able to meet their specific needs and requirements. In this regard, it is important to understand personal needs first before buying a rain gauge.

The size matters a lot because one should consider the location where he or she is going to place the gadget. If the size of the instrument is to affect a purchase-decision, it is essential to shop around for the perfect size to avoid any inconvenience because rain gauges come in several different shapes and sizes.

Always check that it is suitable for the location or purpose you intend to use it for. Larger rain gauges have their own advantages and disadvantages, and this applies to smaller ones as well. If one is also looking for an art piece to place in the backyard or garden to enhance the aesthetic appeal of the home or garden, a large gauge may serve the purpose better.

Features

Design

With the improvements in technology, manufacturers of rain gauges continue to design and produce gauges of different shapes and designs. The availability of different designs out there can be very overwhelming, and finding the right one can prove to be a very difficult task.

With many confusing designs, many people become confused when faced with the difficult task of choosing what they want. Owing to the need to clean rain gauges properly, it is important to purchase designs considered easy to clean and handle.

The design is also important because some designs can handle multiple mounting mechanisms depending on the space the instrument is to be placed. The design is also of paramount importance because some gauges are designed for low rainfall areas while others are meant to measure higher amounts of rainfall in areas most frequented by rain.

In this regard, some have markings to measure rainfall up to 5 inches while others may handle more or less amount of rainfall. It is also important to consider whether the gauge will be hanging on a post or placed on a flat surface off the ground.

Note that some gauges are designed for mounting on other objects while others are better placed on a flat surface off the ground. If looking to mount on a post, consider instruments with mounting vessels in addition to the rain-collection vessels.

Minimalistic designs are best suited for smaller spaces, as they require a small amount of space to collect readings. Some designs with both water-collection and mounting vessels allow for the separation of the two vessels for easy cleaning. The person doing the cleaning simply slides off the mounting vessel for easy emptying and cleaning.

In addition, some are designed with large markings to allow for easy reading of measurements. On the other hand, others feature outstanding finish and designs that make them ideal pieces of art that can be used to beautify the garden. Therefore, users can choose designs based on their visual needs.

Materials

Material

Some are made using materials like stainless steel, aluminum, and even polycarbonate. UV radiation is very important in rain gauges because the absence of which may cause water to evaporate when unable to obtain accurate readings. Others are made of acrylic material, which makes them strong, durable and water-resistant.

Such gadgets are best suited to the outdoor environment. When it comes to choosing a rain gauge, strength and durability are very important properties. Materials like polycarbonate have high levels of UV tolerance. Such materials are able to withstand a range of harsh weather conditions without compromising their quality.

On the other hand, rain gauges made of non-metallic material are generally more resistant to rust than their metallic counterparts. For instance, gauges made of materials containing iron may be more susceptible to rust while polycarbonate material is rust resistant. Users should consider this factor before making their purchase decision because it generally affects the durability of the gadget.

Gauges made of a strong material can also withstand harsh rays of the sun. The tough material may not fade easily, especially if it is of a clear color. Therefore, to easily view the contents of a rain gauge, it is perhaps advisable to go for transparent materials such as glass.

While glass may be cheap in most cases, it is also fragile and may turn out to be costly in the long run because of the constant replacement of broken gauges. Extreme care is also required when handling and cleaning glass gauges, as they may break due to carelessness.

However, glass seems brittle and is more prone to breaking than other materials like polycarbonate. Under extremely tough weather conditions, the glass may not last beyond a year. If the gauge will be used to measure hail as well, then the issue of material becomes of paramount importance because durability is largely determined by the material used.

Accuracy

Mounting Height and Location

Rain gauges should be placed 1.5 meters above the ground. When looking to purchase a rain gauge, it is important to consider the mounting height and ensure that the mounting location is flat to enable the effective collection and measurement of rainfall. Location is important when thinking of installing a rain gauge.

Choosing a rain gauge should be pegged on a specific location. It should be free of any obstacles that may prevent precipitation from being collected in the gauge, but structured in a way that strong winds will not interfere with the gadget. For instance, if the ideal location for a gauge is on a flat surface, it should be in an open space, such as an open meadow in the middle of the forest.

If the gauge is meant for the backyard, the ideal location should be some distance from trees and buildings. Therefore, the choice of a rain gauge should depend on where the user intends to mount the gadget. Purchasing a gauge with the mounting location in mind helps to choose the most ideal instrument for that prospective location, making it convenient for the user.

If the gauge is to be mounted on a post, it is perhaps recommended to consider a gauge with a mounting vessel. The post should also be 2-5 feet in height so that it is far off the ground to prevent bouncing water from splashing into the gauge.

Note that the gauge should extend some few inches above the mounting post so that the gauge is higher than the post. A slanted, rounded or sharp pointed mounting post prevents rainwater from splashing back upwards towards the top of the gauge. A post with a flattened top can easily splash rainwater upwards and into the gauge, causing erroneous measurement and collection of data.

Frequently Asked Questions

q: What is a rain gauge?
a:

This is a specially designed and calibrated instrument that provides accurate measurements regarding the amount of rain received in an area over a certain period of time.

q: Why do I need a rain gauge?
a:

While a rain gauge is not a basic requirement for every homeowner, having one means you do not need to rely on weather reports because you will have the opportunity to collect your own data and analyze it to make important decisions about garden shrubs, flowers, and plants. This simple yet powerful instrument can provide very useful information to help make key decisions about planting, gardening or any other farming-related decision.

q: I am not well-conversant with rain gauges, can I still use one?
a:

You do not require any special training to be able to use a rain gauge. The instrument is easy to install and use. Some gauges are so simple to use that even amateurs and volunteer networks can record readings accurately and with ease.

q: What measurements are used to measure rainfall?
a:

The amount of rainfall in a given area can be measured using millimeters or inches.

q: Must every farmer have a rain gauge?
a:

No. You do not have to own one. However, with the useful data and information provided by a rain gauge, you will be better equipped with critical information that can help make intelligent decisions regarding crops, flowers, and virtually any other farm operation. Important decisions include when to plant, yield or harvest projection, when to harvest, what plants would thrive in a given area, and more.

q: I can get local weather reports, what do I need a rain gauge for?
a:

Local weather reports are very useful in providing specific information about rainfall and other weather-related data. However, do not be fooled by a rain gauge’s simplicity. This instrument can offer more reliable data on rainfall than any other source available elsewhere.

The data obtained is very accurate because it is specific to the farm or area where the gauge was placed and measurements recorded. Note that weather reports are largely based on averages of data collected over a period of time and within a larger area.

The data do not represent accurate weather conditions of a specific garden, plot, land or even village. This is why it is common to hear weather reports of rainfall in your area while in essence no rainfall was experienced. For accurate and reliable weather data, it is recommended to measure and record personal data for intelligent decisions regarding farming and gardening.

q: How many types of rain gauges are available?
a:

There are several different types of rain gauges. However, they can be broadly categorized into two: manual and automatic rain gauges. Beyond the simple manual and automatic classification, the other types of gauges include graduated cylinder, weighing gauges, optical gauges, and tipping bucket gauges. The graduated cylinder is the simplest of them all and is considered the most basic/ standard form of a gauge.

q: What is the difference between manual and automatic rain gauge?
a:

A manual rain gauge applies the direct measurement technique, where it funnels rainfall into a collector funnel before measurements are taken manually and recorded for further action. For automatic rain gauges, measurements are recorded automatically using sensors.

q: How many parts does a rain gauge have?
a:

There are two main components of a rain gauge, which include a collector funnel to channel rainwater for measurement and some mechanism to receive the rainwater and measure it.

q: Is splashing of water an issue when measuring the amount of rainfall?
a:

To minimize splashing and wetting of a surface, the interior of the rain gauge funnel is coated with a special material. This coating prevents water from sticking to the surface of the funnel and affecting measurements. In addition, the funnel is deep enough to allow the inflow of water without the risk of splashing.

q: What if dirt drops inside the gauge, can I still get accurate readings?
a:

To obtain accurate readings, nothing else besides rainwater should get inside the funnel. In fact, the mesh filter ensures that only liquid gets inside the gauge. Leaves, silt, foreign material, bird droppings and other forms of debris are kept off the gauge to prevent possible clogging that could distort readings and measurements.

q: Where do I place a rain gauge?
a:

Rain collecting devices are designed differently to hang to surfaces or be placed on flat surfaces.

q: How far off the ground should a rain gauge be placed?
a:

To obtain accurate readings and prevent groundwater from bouncing off the ground and entering the funnel, place the gauge about 1.5 meters or 3 feet above the ground. At a safe distance off the ground, no water or object can splash from the ground into the gauge, thereby ensuring accurate readings.

q: How do I install a rain gauge?
a:

Rain gauge installation needs to follow certain guidelines in order to get the best results. Identify a safe location in an open place and erect a post on which you will mount your gauge. Ensure that the post is firm before attaching the instrument to it. The distance from a tall building/ tree to the post should be at least twice the height of that particular building/ tree.

q: Are rain gauges manual or automatic?
a:

While they were originally manual, technological advancement has enabled the innovation of automatic gauges to supplement the manual ones.

q: Between a manual and automatic rain gauge, which one is more accurate?
a:

Technological advancement has made it possible to collect and transmit accurate data from rain collecting devices. However, manual gauges have been ranked higher than automatic ones in terms of accuracy and reliability. Due to their ease of use, even amateurs and volunteers observers have no problem using manual gauges.
