Vane Anemometers

Vane anemometers are instruments used to measure wind speed, velocity, and so on, which means one can find the rate at which wind blows in a given time in a matter of minutes. This is not only useful in applications such as wind turbines and sailing but also some indoor segments such as in construction, HVAC systems, and so on. Triplett offers various types of handy and portable digital vane anemometers in multiple configurations. Along with air speed, our portable wind meters can also measure temperature, humidity, light, wind chill, and so on. They come with high precision sensors and offer a fast response time. The air velocity measurement range for most models is from 80 to 3837 and expressed in ft/min.

Know More About Triplett Vane Anemometers

Importance of Airflow Measurement

The significance of airflow measurement in outdoor applications is largely evident. However, it finds applications in indoor segments as measuring the airflow within a system or machine gives an idea about energy consumption, fan motor efficiency, heat losses, and so on. Wind vane anemometers find uses in HVAC systems, boiler systems, open-cell foams and other air tool applications. Vane anemometers are used to measure airflow among other parameters. They have vanes or blades directly facing the airflow. These vanes rotate at a speed based on that of the wind, which means the two are directly proportional to each other. They help measure the amount or volume of air passing from a pipe or duct of a system in a specified timeframe. This can be calculated by measuring air velocity with help of a portable wind meter and multiplying it by the pipe or duct area. All these measures help achieve a comfortable indoor environment, increase the energy efficiency of the machine or system, and ensure good air quality and ventilation.

Benefits of Using Vane Anemometers

Many industrial applications require vane anemometers for wind speed measurement, whether indoor or outdoor. This is because the rotating vane anemometers work in sync with the wind speed. Our devices are absolutely handy, reliable, and easy to use. Also, they have multiple functionalities. Here are some benefits of using our anemometers.

  • Our models are designed to measure accurate air speed as well as may other parameters such as temperature, humidity, dew point, and more.
  • Our anemometers are user friendly and have an easy-to-navigate menu with push buttons and a display screen where the values are clearly visible. You can operate it with one hand.
  • The accuracy rate of most of our anemometer models is high around ±3%. The right value of wind speed positive impacts the accuracy of other calculations and analyses.
  • They have an auto shut down feature and are resistant to water, wind, dust, and harsh industrial environments.
  • You can choose the unit of your preference to measure the values, and this applies for each parameter measured by the device.
  • While a routine maintenance is essential, they are low on maintenance and robust.
  • You get instant and accurate measurements in real time. Also, these anemometers have memory to store past values and retrieve them when required.
  • These anemometers have an auto-adjusting backlit LCD display, which reverses when measuring light.

How Do Vane Anemometers Work?

The force of the wind against the rotating vane makes the vanes rotate at the same speed as of the wind. The flowing wind puts pressure on the vanes because of the pressure difference on the front and rear side of the vanes, which enable their rotation. Based on the number of vane rotations, the wind speed is calculated. Our wind speed anemometers are digital with the vanes mounted on the top of the display screen. They have magnetic sensor which senses the volume of heat displaced from an object or area.

Types of Vane Anemometers

Here are the types of vane anemometers we offer.

  • Basic Vane Anemometers: These are standard devices with rotating blades that rotates at the same speed of wind if directly exposed to it.
  • Hot-Wire Vane Anemometers: To measure air speed these anemometers, use a fine platinum wire that is heated and kept at a constant temperature. The air speed is calculated based on the rate at which the wire cools down. These wires are sensitive and can measure very low speed winds as well. However, they are expensive and require regular maintenance.
  • Multi-Function Digital Vane Anemometers: These digital wind vane anemometers also work on the same principle as above. However, they come with a push button menu, screen, memory, and more. They are enabled for unit conversion, logging maximum and minimum values, and so on. These devices measure air speed and other parameters such as light, temperature, and more in a digital format.

Applications of Vane Anemometers

Here are some common application areas of vane anemometers.

  • Meteorological departments
  • Airports
  • Wind farms
  • Heat-generating industrial equipment and machines
  • Industrial setups and construction segment for ventilation
  • HVAC systems
  • Boiler and heating systems
  • Water treatment process

How to Choose the Right Vane Anemometer?

While we offer assistance on choosing the right anemometer based on your application requirements, here are some tips which may be helpful.

  • Application requirements: Know and analyze your application requirements, whether indoor or outdoor and other specific details. Consider the operating environment and the other parameters you need to measure alongside wind speed. Check the features of various vane anemometers and weigh them against your requirements.
  • Accuracy and precision: The level of accuracy and precision you require is just as important. This is because some applications may require minimum deviation because of their criticality. Check for anemometers designed with tight tolerances in such cases.
  • Measurement range and units: The vane anemometers must be able to cater to your measurement range of air speed among other parameters.
  • Measurement ranges for various parameters are defined for that specific model, such as air speed range and the accuracy level, air pressure and the accuracy level, dew point, light meter, and more.
  • Ease of use: This is an important aspect to consider as the device must be user friendly and accurate. The user must be able to operate, calibrate, test, and maintain the anemometer on their own. This is because you cannot call an expert every time you have some minor issue.
