The standard UNI EN ISO 16911-1 provides for the establishment of a new parameter required for the measurement of velocity and flow rate in gaseous flows: the SWIRL. X1-SWIRL is an accessory designed for use with measuring tubes and probes of any kind and allows to easily check the angle of the tangential flow compared to the axial direction.

  • measuring range: +/- 180°
  • resolution 0.1°
  • zeroing: in any position
