Rakes for flow probes

5-hole probe rake
Our rakes can be outfitted with 4 different measurement types:
  • Multi-hole heads
  • Static pressure taps or rings
  • Total pressure Kiel heads
  • Total temperature Kiel heads


All of our measurement heads (multi-hole probe, total or static pressure, temperature) can be combined in rakes, leading to a higher spatial resolution. Due to the integration of multi-hole heads into the rake, very high measurement accuracy is also available in these products and because of the additive manufacturing process, it is possible to install Vectoflow probes in applications requiring specialized and custom designs. As always, the rakes are very robust due to their one-piece design.
