Gustavsson Flowmeter Test Setup – Applications:

The Gustavsson funnel method This method is used to determine the flowability and apparent density of fine powders, especially metal and ceramic powders, used in additive manufacturing, powder metallurgy, and other precision industrial processes. The method employs a calibrated Gustavsson Funnel The device has a nozzle opening of 2.5 mm, through which the powder flows solely by gravity. The flow time and the mass of the powder passing through are measured to quantitatively evaluate the flow behavior.

Experts value this method because it offers a reproducible and easy-to-perform measurement that correlates strongly with particle shape, surface texture, moisture content, and internal friction. Powders with irregular morphology, high specific surface area, or poor lubrication typically exhibit longer flow times or refuse to flow altogether. The Gustavsson funnel is highly sensitive to small differences in powder handling and is therefore ideally suited for quality control and batch comparison.

In addition to flow time, apparent density is often determined using a standardized density cup. The combination of these parameters enables reliable prediction of powder behavior in real-world processes such as die filling, powder bed deposition, or compaction. Because the method is standardized (e.g., ISO 13517), the results are comparable between laboratories and suppliers, supporting consistent material qualification and process optimization.
