Product information "Calibration in accordance to EN 15518-3/EN15518-4"
 Calibration of sonic anemometer in accordance to EN 15518-4, consisting of two separate tests.
  1.  Accredited calibration of flow speed response of one anemometer.
  • The device under test (DUT) is mounted perpendicular to the flow in the test section of the wind tunnel.
    The predefined orientation is aligned with the flow centerline.
    For each pre-defined test point according to EN15518-3, the wind tunnel is set to a fixed air velocity. After an
    appropriate stabilization period, the DUT and reference air velocities are sampled simultaneously for at
    least 10 minutes, averaged, and reported. A conformity assessment in accordance to the EN 15518-4 and
    ILAC G8 is carried out and recorded in the calibration certificate.

  1.  Accredited calibration of yaw response of one anemometer.
  • The device under test (DUT) is mounted perpendicular to the flow in the test section of the wind tunnel.
    The DUT orientation reference mark (north mark) is aligned with the flow centerline. The wind tunnel is
    set to a fixed air velocity and, after a suitable stabilization period, the DUT is rotated stepwise by
    30° and measured for at least 30 seconds. Once the rotation is complete, the DUT reading and the
    reference angle are averaged and reported. A conformity assessment in accordance to the EN 15518-4 and
    ILAC G8 is carried out and recorded in the calibration certificate.
