Description
Description:
The airflow at swirl diffusers is strongly swirled.
- This makes correct volumetric flow measurement at these diffusers very difficult when measuring exclusively with an impeller anemometer and funnel
- Depending on which direction of flow the swirl hits the impeller, higher or lower measurement results are obtained
- This means that the ventilation system cannot be optimally adjusted
- Patented volume flow rectifier testovent 417 Testo is the only manufacturer to offer a solution for measuring swirl diffusers with equal ease and accuracy
- The patented volume flow rectifier testovent 417, together with a funnel, perfectly supports you in measuring the volume flow at swirl diffusers
- The volume flow rectifier makes it possible to change the swirled flow into an almost uniform flow; which can then be reliably measured with an optional impeller anemometer
- In this set you receive the volume flow rectifier testovent 417 and two funnels for ventilation grilles and disc valves (funnel set testovent 417)
- The funnels and the rectifier can be conveniently transported in the practical carrying bag
- To measure the volumetric flow, you also need a suitable impeller anemometer, which you can order separately.
