Vane anemometer – measurements of wind speed

The vane anemometer is a classic wind speed meter which is now very commonly used, not only outdoors, but also indoors. Easy handling makes it possible to measure airspeed quickly using the impeller anemometer.

In addition to this, many of the instruments also have features enabling volume flow and temperatures to be recorded. This enables even easier analysis of the data and their comparison.

When buying a vane anemometer, it is helpful to consider some important features:

  • measurement of airspeed, volume flow and temperature 
  • direct recording of the measuring values
  • possible combination with smartphone App
  • hold function may be helpful

Measure wind speed – the vane anemometer and its uses

Measuring wind speed is a concept that many users associate above all with outdoor use. However, it is in fact not only outdoors that a wind speed meter is used. In particular, it may make sense to use one for the measurement of air velocities in rooms. Ventilation systems are based on airspeed, temperature and humidity. If these values are not correct or change, it may affect the indoor air quality. The problem here is that it is not always easy to control ventilation systems.

This is where the anemometer comes into its own. Depending on the design, it can very easily be inserted into the ventilation shaft via a telescope, so that it can carry out measurements there. The vane anemometer is ideally suited for this. Most models are fitted with a telescopic probe. This makes it very easy to do a flow measurement in the duct. However, outdoor use is also possible.

Depending on the instrument, you have the option of not just using the vane anemometer to measure wind speed. It can also be used as a flow measurement instrument. Some versions also have the possibility of measuring the dewpoint and wet bulb temperature, as well as wind speeds. These values, in combination with the airspeed and air temperature, can be very helpful and important for your analysis.

These wind speed meters have a built-in vane which can have a different diameter. For flow measurement, you also have the option of using a volume flow hood as well. The combination of different measuring instruments is fundamental, particularly when you are reliant on efficient and detailed values. In this case, it is worthwhile combining different versions here, such as the flow measurement instrument, the thermal anemometer and the volume flow hood.

Benefits of the vane anemometer at a glance:

  • indoor and outdoor wind measurement
  • volume flows and temperatures can be measured 
  • very good recording of values
  • easy handling, even in confined spaces

Anemometers in combination with smartphones

Anemometers in combination with smartphones

You may be one of the users who would very much like to integrate the anemometer into an existing system and would therefore like to ensure that the measurements are directly transmitted. This is very easy to achieve if you decide on a model that can be connected to a smartphone. A special App enables the values to be forwarded directly to the smartphone via this connection. There, they can not only be read out, but also analyzed and compared with other measurements. This means you can quickly establish if there are changes in the air velocity which need to be readjusted. The modern wind speed meter with a connection to a smartphone makes handling easier for you. You do not need to measure the values directly on the anemometer or have these sent to a system. This saves both time and costs.

Direct connection to a smartphone gives the following advantages:

  • quick and easy forwarding of the measured data 
  • problem-free analysis within the App
  • intuitive operation

Wind speed meter with additional measurement data

As briefly mentioned already, depending on the instrument, the vane anemometer is not only capable of measuring air velocity. Other measurement data can also be recorded by the anemometer. There are thus some versions which are able to measure airspeed, humidity and temperature. A combination of these data can provide information about important aspects.

If you work in the air conditioning field or if you need more data, you can also decide on an anemometer that is able to determine the dewpoint. This means that sophisticated analyses are also possible.

Wind speed measurement for spot measurements

The vane anemometer can also very easily be used for spot measurements. These short measurements provide a quick overview of the required data. In addition, the instruments are also able to be used solely as wind meters in the outdoors. If you choose a model from Testo which you would like to use as a wind speed meter, you should get a version which is able to display a variety of units. Displays that show values in m/s, fpm, mph, km/h and kts are common. It is then possible to carry out Beaufort and windchill calculations based on these values.

Advantages of wind speed measurement using an anemometer:

  • wind speed measurement in a variety of values
  • windchill calculation 
  • Beaufort calculation

Ordering a wind speed meter from Testo

If you have found out all about the vane anemometer and if you have been able to establish that this type of wind speed meter is the best solution for your purposes, then you can now take your time to compare the individual instruments in Testo's range with one another.

Handling and features, along with the measurement parameters and measurement options which are available to you, are important factors when it comes to making a choice. You can then carry out effective measurements with little effort.
