Measurement technology
Flow measurement probes from Vectoflow combine the principle of conventional multi-hole-pressure-probes with modern rapid manufacturing. As a result, our probes are very robust and can be adapted perfectly to your application in terms of geometry and choice of material.
The measurement chain
Compared to other measurement methods, multi-hole-probes are easy to install and easy to use. A simple measurement can be performed in minutes.Manufacturing & calibration
The customized probe is manufactured by Vectoflow and calibrated for your application.
System integration
The probe is integrated into the test rig and aligned using a reference surface.
Data collection
A pressure scanner acquires pressures at the probe holes and transmits them to the data acquisition system.
Analysis
Vectoflow software performs data analysis and returns the calculated flow quantities.
Multi-hole probes
The use of multi-hole probes is an easy and precise way to measure a fluid flow. By measuring differential pressures at the head of the probe the following flow quantities can be determined:- Total and static pressure
- Angle of attack
- Velocity of the flow
Variants
You may choose different pressure probe head types dependent on the specific application and the required accuracy. Head geometry as well as the amount of holes in the probe are chosen to achieve the best results. Options include 3-, 5-, 7- hole probes or a fully customized probe. To achieve optimal results, the probe material is selected based on the test enviroment and application.
