Alnor Rotating Vanes

Rotating vane anemometers remain a go-to solution for face velocity and volumetric flow estimation at grilles and registers. Alnor rotating vane instruments are engineered for repeatable readings and straightforward operation, supporting research workflows where speed and robustness are essential.

Key advantages for R&D:

• Mechanical sensing delivers stable readings in moderate-to-high flow conditions, even in real-world setups.
• Simple controls help reduce training time for student labs and multi-team projects.
• Optional data output supports time studies, averaging, and documentation across test points.
• Rugged build quality is well-suited to frequent travel between lab spaces, mockups, and field sites.

Where they excel:

• Face velocity surveys for supply and exhaust devices.
• Cross-checking volumetric estimates against capture hoods and pressure-derived calculations.
• Trend analysis for component prototypes and grille designs.
• Teaching labs that require visible, intuitive airflow measurement tools.

Complementary instruments:

• Use micromanometers for pressure and pitot traverses inside ducts.
• Deploy thermal anemometers where low-flow mapping is required.
• Apply capture hoods for direct volumetric measurements to validate vane-based calculations.

Alnor rotating vane anemometers contribute to a complete ventilation measurement toolkit, enabling teams to allocate the right instrument to each flow regime. Contact TSI to discuss model options, data logging capabilities, and accessories that support your test protocols and reporting requirements.
