An anemometer is an important instrument in weather. It helps to analyse the speed of wind and give this information to the researcher or user. For those that want to have an array of weather devices at their disposal, this is a popular one to have. Yet, for those who are new to the device or who are unsure, knowing what to look for in a device can be intimidating. To help you get started on purchasing the best anemometer, the following is a comprehensive and easy to understand anemometer buying guide for you to use before purchasing.

The Style: There are several different styles of anemometers from which you can choose when buying. These options include:

  1. The Cup Style: First, there is the cup anemometer. This device actually uses cups to test and analyse wind speed. There are typically at least three cups on this device and the rotation and sensors within provide the wind information. The benefits of this device include the fact that this device is not directionally specific. It will find the wind to analyse. But, unfortunately, it requires a strong wind at high velocity to work well. It is not great for researching and it may not take wear and tear well. Specifically, it can respond very badly to icy conditions.
  2. The Hot Wire: The hot wire anemometer varies greatly from other options. It utilizes wires to identify and analyse winds. Specifically, it provides analysis of whether the wind is cooled down or heating up. This is done through a current system. What is great about this is that there are no rotating mechanisms. That helps to keep the device working longer and with more resistance to wear and tear. It also has a high accuracy in the information it provides. Further, this device is smaller. Unfortunately, because it is smaller, it can be damaged more readily. It also does not respond well to ebbs and flows in temperature.
  3. The Tube: Another option that you will have in an anemometer is the pilot tube device. This device measures pressure and then transitions this information into wind data. It focuses information on static pressure and air velocity through this pressure. What is great about this device is that it can handle high winds and high temperatures. It is small, too, and has no moving parts. This helps to ensure that it lasts longer without as much mechanical breakdown as other options. Further, the information that it provides is quick and accurate. But, like anything, it has its faults. It is great in high velocity and poor in low. It does not do well with ebbs and flows in speeds and it must always be pointed at the wind.
  4. Sonic Option: The most advanced of choices in these devices is the sonic anemometer. This device utilizes sound waves to provide information on the wind. Specifically, it looks at ultrasonic sound waves and pulses. This device is very weather resistant and that means that ice is less of an issue. It, too, has no rotating mechanisms which prevents against wear and tear. It is, however, easier for birds to sit on this device and it is extremely expensive, too.
  5. The Vane: The vane is similar to the cup anemometer. But, unlike in the cups, the sensors in this device are in a windmill form. In order to analyse the wind, it must be parallel. The great things about this device is that it can handle the elements and works well. They can also sustain higher winds.
  6.  The Style: Yes, there are many options in the type of anemometer that you will have to choose from, but there are also stylistic and design choices to be made as well. One of the first things that you will have to consider is the overall size of the device. These devices come in a range of different options and your placement is going to matter greatly in what size you choose. If choosing a cup design, you will also have to consider the number of cups that you want. Remember, with the cups that there is more room for mechanical concerns and replacement can become an issue, yet they are still perfect for some budgets and air spaces. Cabled designs provide more options in accuracy but can be susceptible to damage, too, so consider all of this when buying.
  7. The Hue: Anemometers come in a wide variety of colours. Some are more brightly hued than others. The colour is a personal choice that is actually fun to choose. Consider the schematic you are seeking and think about the options in that colour palette. This will help you to identify the device that you want and need.
  8. The Materials: Construction matters when it comes to weather equipment. The anemometer is no different. The materials that are used greatly impact the overall design and efficacy of the device. They also directly contribute to the durability, too. Think about if you live in an area with severe weather concerns. The more icing and the more rain, the more sturdy you will want the device to be.
  9. The Extras: Anemometers come with extra features that can greatly enhance the device. There are those that have easy clean-up features. There are those that have digital elements. There are also those that protect against electrical interference. Look at your budget and see if they are worth the additional cost.

Choosing Made Easier
With the above information, you are in a better place to make a wise choice in an anemometer. Use this as your guide and make shopping easier. Remember, if you are in a storm area or are susceptible to weather problems—or if you just like to research the weather—this is a great device to have in your arsenal. Have fun, take your time, and choose the one that is right for you! Oh, and have fun shopping!
