Air generally wants to move from a zone of high pressure to a zone of low pressure. It is the result of differences in air pressure around the globe. Wind gauges are often present on the top of cranes to monitor whether the wind is not too strong.Paragliders and glider aeroplanes use the data from the anemometer to ensure conditions are safe to fly.Anemometers are used in the sailing and maritime sector to measure wind speed and direction.Physicists use anemometers to study the way gasses move.The invention of the anemometer has greatly improved our knowledge about weather processes.Īnemometers aren't just used in the meteorological field - here are some other use cases: It is thus very important that we can measure wind speed to better understand it and make better weather forecasts.ĭata from weather stations with anemometers and doppler radars with wind speed measuring capabilities are used by big computer models to make weather forecasts. The Importance of the Wind Speed Meterīesides temperature, precipitation and humidity wind is one of the main meteorological parameters. From ultrasonic wind gauges to hot wire anemometers and doppler wind speed meters, which are often used in weather radar to measure the movement of air. But in the last century, there have appeared some more futuristic wind meters. Over the years, the basic anemometer hasn’t changed all that much. However, the wind vane is still by far the most common device for measuring wind direction. With this addition, the speed of the anemometer moves faster or slower depending on whether the tag is moving with or against the wind, and from this the wind direction can be calculated. This was achieved by adding a tag to one of the wind cups. In 1991, Derek Weston developed the three-cup anemometer even further, by added the ability to measure wind direction as well as wind speed. One of the more notable improvements of the wind meter was the invention of the three-cup wind meter by John Patterson in 1926. Over the centuries, it has been improved by a number of different people. by Italian author and architect Leon Battista Alberti. The first wind gauge was created around 1450 A.D. We’ll go into more detail about each of these later. Nowadays anemometer is still the most commonly used term for referring to a wind speed measuring tool, especially in the scientific field.Īnemometers come in different types: handheld anemometers, digital anemometers, wind gauges part of a more advanced home weather station and more. The word anemometer actually originated from the Greek word “anemos”, which translates to “wind”. Since the word anemometer isn’t the easiest to say or spell, wind speed measuring devices are often referred to as a wind gauge or wind speed meter. In this case, it is worthwhile combining different versions here, such as the flow measurement instrument, the thermal anemometer and the volume flow hood.A Beginner's Guide to Anemometers What is an Anemometer?Īn anemometer is a measurement device that measures wind speed. The combination of different measuring instruments is fundamental, particularly when you are reliant on efficient and detailed values. For flow measurement, you also have the option of using a volume flow hood as well. These wind speed meters have a built-in vane which can have a different diameter. These values, in combination with the airspeed and air temperature, can be very helpful and important for your analysis. Some versions also have the possibility of measuring the dewpoint and wet bulb temperature, as well as wind speeds. It can also be used as a flow measurement instrument. However, outdoor use is also possible.ĭepending on the instrument, you have the option of not just using the vane anemometer to measure wind speed. This makes it very easy to do a flow measurement in the duct. Most models are fitted with a telescopic probe. The vane anemometer is ideally suited for this. 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. This is where the anemometer comes into its own. The problem here is that it is not always easy to control ventilation systems. If these values are not correct or change, it may affect the indoor air quality. Ventilation systems are based on airspeed, temperature and humidity. In particular, it may make sense to use one for the measurement of air velocities in rooms. However, it is in fact not only outdoors that a wind speed meter is used. Measuring wind speed is a concept that many users associate above all with outdoor use.
