What is The Use of Anemometer; Details You Need to Know About Wind Meter
What Is a Digital Anemometer?
A digital anemometer is a device that measures wind speed and direction. It is also called a mutual weather station instrument. The word anemometer is derived from the Greek word “anemos,” which means wind. This wind speed instrument is used in meteorology or aerodynamics to detect the weather casting. Leon Battista Alberti invented the anemometer around 1450.Unexpectedly, it was changed little from its original invention in the 15th century! It still uses mechanical movement to measure the rate of movement and then presents the information.
However, Leonardo da Vinci reinvented the device. He made it more accurate and easier to measure wind speed. Numerous others developed later versions of the anemometer.
Dr. Andrews Pflitsch made the latest development in anemometers, including the sonic anemometer, in 1994. For more historical facts and more information about other new technologies used in anemometers, please the following link on Brief History of Anemometer blog post.

Let’s see what exactly an Anemometer is and how does it work!
How Does a Digital Anemometer work?
Along with a digital anemometer, many other kinds of anemometers measure the wind’s angle. For example, we have used a wind vane. The wind vane design is constructed to attract the center of gravity directly over the pivotal axis so that the pointer moves freely at its desired axis. During this procedure, we also count the placement of surface area that is unequally divided. The side with the larger area is blown away from the roller so that the smaller side with the pointer rotates to face into the wind direction. In the new inventions, the wind vane has directional indicators beneath the arrow associated with the geographic directions.
Propeller anemometers work in much the same way. Like small wind turbines, they use small propellers to control their generators instead of rotating cups—the generator links with an electronic circuit. Then Anemometer gives instant data about wind speed on a digital display.
A decent anemometer will bounce a wind speed reading exactly to about ±0.5 m/s (±2km/h or ±1mph), but that is often far more precise than you need. Remember that the wind speed is not constant; it fluctuates all the time.
How to Measure the Wind Speed?
In this digital world, we have seen gigantic progress in the electronic market. Nowadays, we have a wide range of devices and instruments to measure climate changes, low and high temperatures, and the measurement of wind speed. Here, we describe a few digital devices which measure wind speed.
Anemometer Basics and Fundamentals
Measurement technology provides devices for optimizing production processes and dosing operations. Since most production systems have a continuous operation, the measured values must indicate the instantaneous conditions or the instantaneous values. So, the flow rate as a time-dependent value is essential. There are three methods used to measure the flow velocity:
• Pitot tubes
• Rotating vanes
• Thermo Anemometer probes
Airflow measurement instrumentation is one of the most effective methods to test and confirm components. These test instruments are known as anemometers. An anemometer is a device designed to measure speed, intensity, amplitude, and direction. Anemometers are essential techniques used by meteorologists at weather stations to analyze what conditions occur. Anemometers measure wind speed in feet per minute (FPM). Wind speed is typically defined as the velocity of the wind. Also, it is defined as the movement of air in the atmosphere from high pressure to low pressure because of temperature changes. Usually, anemometers are classified as Constant-temperature anemometers and Constant-power anemometers.

Types of Anemometer
There are different types of anemometers on the market, each with unique features; some are very common, while others are scarce. Some of them measure more than only wind speed. The measurement can be done thermally (hot wire anemometers), by wind cooling of a heated wire as well as mechanical (side wheel wind measuring meters) or by pressure (pitot tube anemometers) based on construction type. The newest technology uses ultrasonic and Laser methods to obtain accurate wind measurements. These types of anemometers are costly compared to the more value of a better result.
Choosing a suitable anemometer for your specific needs can often be tricky. Usually, anemometers have two main groups:
• Velocity anemometers
• Pressure anemometers
Anemometers based on shape and size have several types which we explained some of the important ones below:
Mechanical Anemometer
They are slightly more than an electricity generator straddling in a sealed-up metallic chamber with an axle distended upward from it. On the upper part of the axle, more than a few large cups catch the wind and make the generator spin from place to place. Propeller anemometers work in much the same way. Like miniature wind turbines, they use small propellers to power their generators instead of spinning cups. As the wind blows, it spins the fan blades and a small generator to which they are close, which works a bit like a push-bike motor. The generator connects to an electronic anemometer circuit that gives immediate information on the digital anemometer’s wind speed display.
Ultrasonic Anemometer
An ultrasonic anemometer has two or three pairs of sound whisperers and headsets at right angles. Each whisperer in the wind continuously beams high-frequency sound to its particular earpiece. Electronic anemometer circuits calculate the time it takes for the sound to make its drive from each teller to the equivalent receiver. Depending on how the wind blows, it will affect some sound beams more than the others, slowing them down or fast-moving them up very slightly. The circuits measure the alteration in the rays’ speeds and use that to examine how fast the wind is blowing.
Doppler Laser Anemometer
The laser Doppler anemometer sends one or more safe electromagnetic laser rays straight up into the air that serves as the reference beam and detects the reflected rays back down from the dust constituent part, water dews, and so on. Wind movements shake those floating particles around, so the measurement of the sunbeam slightly changes compared to the reference beam. The change in frequency is called a Doppler shift, and it is much like the way a fire engine alarm changes pitch from the note to top to toe as it speeds past you. By calculating the frequency shift, you can exactly measure the speed of whatever caused it.
Hot-Wire Anemometer
If you are aware of the idea of wind chill, you will know that the wind cools belongings as it blows past them in a very predictable way. So, calculating the quantity of cooling the wind produces on an object of a certain temperature is a secondary way to figure out the speed of that blowing wind. This is how does hot-wire anemometer works. It uses an electrically animated hot piece of wire similar to the thread in an out-of-date light bulb past which the wind blows. As the wire chills, its electrical values change can be measured to figure out the amount of cooling and the wind speed. Hot-wire anemometers are principally well-matched for measuring turbulent airflow, and they are extensively used in manufacturing for things like measurements of fluid flow in airplane engines.
There are other types of anemometer based on shape and sizes that come in the following which we explained in the Types of Anemometer article.
• Cup Anemometer
• Vane Anemometer
• Windmill Anemometer
• Ping-pong Ball Anemometer
• Pressure Anemometer
Choosing the Right Anemometer | A Complete Buying Guide
Since the wind is an essential factor in many situations or tasks, its measurement is a significant advantage. It allows us to determine the maximum speed of a gust of wind immediately. It usually consists of several small cups connected to a vertical rod (cup anemometer). It counts the number of cup revolutions to measure the wind's speed.
Choosing the correct one for your application can be complicated. Before selecting any anemometers, you need to know entirely about them. Also, you have to consider every type of anemometer has a different working principle and is designed for a specific purpose. Also, it is necessary to fully understand the environment where you want to make the measurements. Here we have made it easy for you; we gathered all the essential information regarding Choosing The Right Anemometer ; please read up to make the best choice.
How to Use an Anemometer
Anemometer is a crucial device for meteorologists searching for weather patterns. It determines the number of rotations to measure wind speed; the faster the rod turns, the faster the wind blows. When you purchase a digital anemometer, you should know how to set up and use it to find the speed of wind gusts. Anemometers come with an instruction manual. You need to read the instructions carefully before using the device. There are four steps for using an anemometer as follows:
• Reading the instruction provided
• Installing the battery
• Turning on the device
• Choosing your preferred measurement setting

Frequently Asked Questions About Anemometer
What is the difference between a weather vane and an anemometer?
Anemometers are devices to calculate wind speed and wind vanes determine wind direction. An ordinary wind vane has a pointer in front and fins in the back. When the wind blows, the wind vane directs into the wind. If the conical cups are removed, it is only about Wind Direction.
What is the unit used to measure wind direction?
An anemometer indicates the direction of the wind in North (N), South (S), East (E), and West (W), or in North azimuth degrees (0-360°) [number indicates data feeds in square brackets], with 0° = North. It means that a south wind blows from the south and a north wind blows from the north.
Which type of anemometer is used in river hydrology and high-tech jet engines?
Laser Doppler anemometer.
