For flows with high amounts of swirl, such as in the wake behind automobiles, our 12-hole Omniprobe is an ideal measurement choice. A micro-machined spherical tip accommodates 12 pressure ports that allow for measurement of +/- 150 degrees of flow angle.

Omniprobes are frequently used for high-angularity wake measurements around automobile wheels, wake measurements behind automobiles and rolling-road wind tunnels.

Omniprobes are also ideal in applications where the predominant direction of the flow is not known in advance or where the probe may see a complete reversal of the flow during testing, such as in wind engineering or combustor swirl flows.
