The quality of the indoor air depends
crucially on whether the air input or output volume flows are optimally
adjusted. For this reason, the measurement is taken directly at the outlet
during adjustment work. However, inaccessible ventilation ducts also make
measurements at outlets necessary.
At swirl and plate outlets or ventilation
grilles however, turbulence is created, which can falsify the measurement
results.
In order to be able to measure these
non-uniform flow profiles, it is essential that a funnel measuring instrument
with a flow straightener is used. Patented volume flow straighteners from Testo
guarantee the greatest level of accuracy, even in strong air turbulence.
