Multi-hole Probes with Standard Geometries
Conventional multihole-probes are available in 4 different geometries: Straight, L-shaped, Cobra and Drilled elbow.
Details
Multi-hole probes are easy to install in your test set-up and enable the simultaneous measurement of pressure, velocity and the angle of attack for a flow. Vectoflow probes are available in standard geometries such as straight, L-shaped, cobra or custom geometries as well. The probe lengths, tip diameters and tip geometry can be adapted to your requirements. The one-piece design makes them very robust. We also offer probe calibration and software. We would be pleased to assist you with the selection of the most appropriate standard geometry for your application.Specifications
