Multi-hole probes with standard geometries

Conventional multihole-probes are available in 4 different geometries: straight, L-shaped, cobra and drilled elbow.


The easy application of multihole probes makes it possible to measure pressure, velocity and the angle of attack of a flow at once. The robust vectoflow probes are availabe in standard geometries like straight, l-shaped or cobra or in custom geometries as well. The lengths, top diameters and top geometry can be adapted on the special application of your measurement case. In addition we also offer the suitable calibration and software. We are pleased to help you with the choice of the appropriate standard geometry.
