    3. Vane anemometer – measurements of wind speed

    Vane anemometer

    The vane anemometer is a classic wind measuring device that is very popular today, not only outdoors but also indoors. Easy handling makes it possible to measure airspeed quickly using the vane 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

    • Can be used with smartphone App

    • Hold function may be helpful

    Measure wind speed – the vane anemometer and its uses

    Measuring wind speed is a term that makes many users think of 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.

    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 to use, even in confined spaces

    Depending on the instrument, you have the option of using the vane anemometer to measure more than just air velocity. 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.

    Other flow meters

    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 to combine different instruments, such as the flow meter, the thermal anemometer and the volume flow measuring hood.

    Anemometers in combination with smartphones

    You may be someone who would like to integrate the anemometer into an existing system and therefore like to ensure that the measurements are transmitted directly. This is possible if you opt for a model that can be connected to your smartphone. A special app is used to transmit the values directly to the smartphone via this connection. Here they can not only be read, but also analysed 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.

    Wind speed measurement for spot measurements

    The vane anemometer can also 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 outside.

    If you choose a Testo model that you want to use as a wind meter, you should choose a variant that is able to display different 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
