“…Such anemometers are commonly used in research related to boundary layer and velocity profile measurements [17,18]. The hotwire measurement system and the probe used were included in the CCC2002 measuring module [19][20][21]. Before the experiments, the static characteristics of the thermo anemometric system were precisely determined, and the whole system was adjusted to the value of the reference velocity.…”

The complex ventilation system development process is associated with the stages of modelling, design, execution, and testing. Each of these steps requires the use of measuring equipment that is capable of determining the basic parameters of the flow. In the process of calibrating instruments for measuring flow velocity, one of the limitations is the size of the calibrated devices positioned in the test section of the wind tunnel. This is related to the change in the flow condition within the vicinity of the calibrated anemometers, which is caused by the blockage effect. Instruments with significant dimensions in relation to the cross-sectional area of the wind tunnel test section may have an impact on the reference velocity as indicated by the standard. In such cases, the calibration results may be affected by additional systematic error. This article presents a study of this effect using a real case of a calibration laboratory and commonly used sensors. The influence of different types of air velocity sensors on velocity profiles in the measurement standard area is also investigated. Additionally, the area of the blockage effect is described. The obtained results indicate the possibility of a proper placement for the measuring standard due to minimization of the flow-blocking effect.

“…Nevertheless, this is a very accurate and robust instrument, it is very well known (as it has been thoroughly studied during the last 150 years [ 25 ]), and its calibration is inexpensive. It is also worth mentioning that different solutions can be found in the literature to improve the dynamic response of the cup anemometer, from the proposal of low-inertia cup anemometers [ 26 ] to the development of signal-processing techniques, which address both the dynamic response and the overspeeding problems [ 27 , 28 , 29 ].…”

This paper shows wind speed measurements from the TASEC-Lab experiment in a stratospheric balloon mission. The mission was launched in July 2021 from León (Spain) aerodrome. Measurements of horizontal wind speed in relation to the balloon gondola were successfully carried out with a cup anemometer. According to the available literature, this is the first time a cup anemometer has been used in a stratospheric balloon mission. The results indicate the need to consider the horizontal wind speed from the balloon ascent phase for thermal calculations of the mission.
