Focus Flow measurement technology

Specialising in advanced flow measurement technology, Vectoflow probes harness the principles of the Bernoulli effect to precisely assess fluid flow pressure, velocity, and angle of attack. By analysing the pressure distribution at the probe tip, our probes enable accurate determination of crucial flow parameters. The precision and range of angular measurement achievable with flow probes are directly proportional to the number of holes located at the probe tip. As such, a higher number of holes enhances both precision and coverage in flow measurement applications.

Omni Iprobe

Vectoflow’s Omni-iProbe is a compact and lightweight plug&play system for measuring flow speeds and angles of attack for mobile and wind tunnel applications. By combining a probe with a data acquisition system, fluid dynamic measurements have never been so fast and easy!

Conventional multi-hole probe

Multi-hole probes offer straightforward operation to enable concurrent detection of critical aerodynamic and thermodynamic variables:

GEOMETRY

The Vectoflow manufacturing process allows you to flexibly shape your probe to fit your application exactly. We realize probe diameters starting from 1.2 mm and lengths up to 250 mm (standard) as one integral design. Longer probes are getting realized via a hybrid design.

The connection (e.g. square, hexagon) of the probe is flexibly adapted to your requirements.
Simple connection of the hoses, Quick Connectors, Swagelok and many more is possible.

HEAD SHAPE

In addition to the standard cone, facetted- and hemisphere shapes, other geometries are possible.

CoCr Alloys
Stainless steels (e.g. 1.4542, 1.4540)
Ceramics (Al2O3, SiNi3)
Plastics (PEEK, PA12, ABS, Resin)
