Adjustable air damper with flow measurement, in particular a louver damper with flow regulator function

Abstract

The first pressure probe (3) is located on the inlet side of the channel and includes an elongated body that is located in the channel inside the body parallel to the axis of rotation of the blade (2) and this body has at least two openings (5) on the inlet side. The second pressure probe (4) is located on the outlet side of the channel and includes an elongated body that is located in the channel inside the body parallel to the axis of rotation of the blade (2) and this body has at least two openings (5) on the outlet side. Both pressure probes (3, 4) are located at the same height of the channel and are preferably located in a horizontal plane that passes through the center between the axes of two adjacent blades (2). The opening (5) is formed by an opening (51) in the pressure probe (3, 4) and / or a nozzle (52) that extends from the pressure probe (3, 4). The pressure probe (3, 4) preferably has three orifices (5), the second orifice being in the center plane and the first and third orifices being symmetrically spaced from the second orifice.
