Testo 0554 4172 Testovent 417 Flow Straightener

Testovent 417, a novel volume flow straightener, provides optimal support for measuring flow velocity at swirl outputs. The swirling flow can be redirected by the volume flow straightener into an essentially uniform flow, which can then be accurately measured using vane probes or an anemometer.

The only manufacturer offering a solution to the issue of measuring at swirl outlets equally simply and precisely is Testo. Testovent 417, a novel volume flow straightener, provides optimal support for measuring flow velocity at swirl outputs. The swirling flow can be redirected by the volume flow straightener into an essentially uniform flow, which can then be accurately measured using vane probes or an anemometer. Depending on which direction the swirl affects the vane, measurements at swirl outputs without the volume flow straightener yield lower or higher measurement values.

The optional measuring funnel Testovent 417, optional vane anemometer Testo 417, or the vane probes (Ø 100mm) of Testo 435 and Testo 480 are used in conjunction with the volume flow straightener.

Features:

• Improved measurement of volume flow that is not reliant on the direction of swirl

• Trustworthy measurements on swirl outlets

• Retrofittable flow straightener for Testo funnel sets already in place

Applications:

Systems for air conditioning and ventilation
