Omniprobe

Omniprobe is a marked improvement on the angular resolution of the multi-hole probes. With the use of 18 holes distributed on a spherical surface, streams can be evaluated from virtually any direction. The probe is able to detect velocity vector tilted up to 165° with respect to the probe.

These features allow measurement in highly inclined streams or even in reverse flow. The probe is useful in the exploration of wakes of bluff body, cars, wings, atmospheric wind.

Calibration is a fairly costly process that requires at least 7000 different tests. The diameter of the spherical head is about 10 mm. The Mach number can vary from 0.02 to 0.95.
