What to Look for Before Buying Rain Gauge?

Types of Rain Gauge

Rain gauges, like all measuring devices, have undergone an irreversible digitization process in recent years: conceived as analog instruments, they too were soon integrated into automatic control and measurement systems.

Leaving aside the by now antiquated analog rain gauges, for digital rain gauges, we can distinguish different construction and implementation typologies.

First of all, there are rain gauges whose operation is linked to a weather station: the user is notified of the start of precipitation using appropriate application software; subsequently, by processing the acquired data, the application allows you to adjust the subsequent watering for your garden.

Then there are the manually operated rain gauges, generally consisting of a graduated container placed at a certain height from the ground using a rod to be fixed to the ground.

Via intermediate between the two previous categories, the electronic rain gauge allows to obtain, by wireless transmission and up to tens of meters away, all the data of interest relating to the most recent atmospheric showers.

Calibration and Precision

Each measuring instrument on the market has a cost directly proportional to the quality, precision, and resolution of its measurement. For the same design technology, the cheapest rain gauges provide the coarsest sizes, while the most expensive ones are the ones that ensure decisive measures more accurate.

Compare the prices to compare how the manufacturer has calibrated the reference graduated scale and the various sensors possibly integrated.

We believe that this aspect of precision is to be particularly taken into consideration when deciding to buy a garden rain gauge to establish, optimize costs, how and how to reduce the supply of water to plants and flowers.

Network Interconnection

Another element of primary importance that we want to highlight in this guide to choose the best brand of rain gauge is the possibility of integrating it within a home or industrial network for the remote control of various parameters linked, for example, to automated irrigation systems.

Again, of course, it is up to you to find the right compromise between economic and technological aspects: the more the rain gauge can be integrated and adapted to the different types of networks, the more it will respond better to your needs.

How to Use a Rain Gauge?

The rain gauge is a measuring instrument that aims to collect information about the rainfall. It is used in various fields, such as meteorological, hydrogeological, but also in the agricultural and domestic fields. If you don’t know how to use it, we recommend reading this article.

The Typologies

Before using the equipment, it is necessary to identify which model it is since there are mainly three types of products on the market: manual, with electric and electronic sensors. Those with electrical sensors connect to a weather station via software and notify the user of the arrival of rain.

The data acquired by the precipitation are processed, regulating the subsequent watering of the garden or vegetable garden. The manual ones are composed of a graduated container, positioned on a rod.

The electronic rain gauge is a middle ground between the two types: it works wirelessly and returns all the most important information about the latest atmospheric showers.

Do Not Neglect the Instructions for Use

As we have seen, thanks to technology, the rain gauge has evolved not a little, and the most modern include additional functions, which may vary depending on the model. For this reason, it is important to read the manufacturer’s instructions to understand each function and use it correctly.

Read the manual with the tool in front of it, so that you can configure it at the same time you read a certain paragraph. Following the instructions given by the manufacturer of that specific item will avoid inconvenience, malfunction, and waste of time.

Where to Place the Rain Gauge?

Deciding where to place the rain gauge is not a choice to be made in an impromptu way since the correct location is crucial to have accurate data. So take your time and make the right assessments. Avoid places near trees, because they could deviate the trajectory going to compromise the result.

More generally, you will have to position it away from any type of obstacle. Also, the equipment must be positioned at least 0.5 meters from the ground, up to a maximum of 2 meters in height. Stability is also important, with a stronger than usual gust of wind it risks tipping over.

Connection with Devices

The technological and electronic conversion of these devices, among other things, allows the rain gauge to collect data and transmit them remotely to the smartphone, tablet or computer, through applications provided by the manufacturer.

These apps allow the rain meter to connect to a specific website and, in some cases, to the weather stations and then communicate the forecast to you.
To obtain this performance, you must, therefore, install the software on the device on which you want to receive notifications.

After installation, from a smartphone or another device, connect to the rain gauge to check the amount of rain that has recently fallen. Sometimes, those who do not have a smartphone or tablet can take advantage of this service by connecting to the website to have the same information available.

Other Suggestions

As we said, most of the time, it is possible to connect the rain gauge to mobile devices or the PC, the advantage is also that of being able to obtain data to be compared.

However, if this function is not available, we advise you to write down the information on a notebook so that you can be sure that the rain gauge is working properly.

Reading the instructions will allow you to take full advantage of all the options available—for example, the possibility of controlling the outside temperature or the time and date of the day. Some models act as an alarm. As it is easy to understand, knowing the interface of your device can be very interesting and useful.
