Multi-hole Probes

Multi-hole probes allow measurement of the full 3D flow velocity vector.

We have developed sintered solutions that both reduce the probe head
size and increase the operating envelope. We can produce a 5 hole probe with a diameter as small as 6mm.

Measure full 3D flow vector

Probe diameter down to 6mm
