FST 144 Flow Scan Test System
Automated flow-scanning test system for characterising downstream air-velocity profiles and turbulence of filters, ducts and other flowed-through components across multiple airflow conditions.
Model Overview
| Model | System purpose | Standards / method | Core fit |
|---|---|---|---|
| FST 144 | Automated hot-wire scanning of downstream velocity fields and turbulence behind flowed-through components | Application-specific airflow methods | Flow-field characterisation, sensor-position optimisation and CFD-model validation |
Key Features
Automated planar scanning
A traversing system scans the downstream outlet plane with a hot-wire anemometer.
Velocity and turbulence analysis
Measures air velocities from 1 to 40 m/s and captures rapid fluctuations for turbulence assessment.
Wide airflow range
Supports test flows from 20 to 900 m³/h, with expansion up to approximately 1200 m³/h.
High pressure-drop capability
Accommodates significant pressure losses across specimens, connectors and hoses.
Graphical data evaluation
Fast data acquisition and visual presentation simplify interpretation of the measured flow field.
Simulation correlation
Measured velocity maps can be compared with CFD and other airflow-simulation models.
