Measuring air velocity
Air velocity influences the functioning of ventilation systems, flight safety and meteorological measurements. METAS calibrates anemometers in its wind tunnel and guarantees reliable measurements for industry, research and safety-relevant applications.
Measuring air velocity in everyday life
Air velocity measurements are used to control ventilation systems, make meteorological observations and emission measurements, and to assess wind conditions in aviation and sports.
Air flows are influenced by temperature, pressure and other ambient conditions. In order to guarantee reliable measurement results under these challenging conditions, METAS calibrates measuring instruments that are designed to determine air velocity.
Typical applications of air velocity measurement
Air velocity measurement is relevant to various fields:
- Building and ventilation technology: for controlling indoor air quality, optimising energy efficiency and measuring comfort
- Aviation: for navigation, flight safety, wind tunnels and runways
- Energy generation: for wind turbines and power plant chimneys
- Science and research: for meteorology, fluid mechanics and environmental monitoring
- Industry and manufacturing: for clean rooms and drying processes
- Sports and leisure: for shooting, archery and sailing
Our services in the field of air velocity
In the field of air velocity, we calibrate various types of anemometers in the range of 0.1 to 40 m/s, including:
- Hot wire anemometer
- Vane anemometer
- Ultrasonic anemometer
- Pitot probes
Measuring methods and technologies
We use the following measuring equipment and reference equipment for the calibration of anemometers:
- Wind tunnel with a test section of 75 cm x 40 cm
- Reference anemometer (vane anemometer or pitot probe) as secondary standard
