Aircone Flow Hoods
Aircone Flow Hoods are a fast and accurate method of maximizing
the usefulness of your 4-in. (100 mm) rotating vane anemometers.
For a modest investment, you can enhance the capability of your
rotating vane, turning it into an air volume flow balancing tool.
Features and Benefits
• Rectangular and circular cones available
• Measures volumetric flow at grilles and diffusers
• Reads air volume quickly and accurately
• Excellent choice for small grilles
