Gustavsson Flowmeter Kit - Features

Das Gustavsson Funnel method is used to evaluate the flowability and apparent density of fine powders, especially metallic and ceramic powders used in additive manufacturing, powder metallurgy, and high‑precision industrial processes. The Gustavsson Flowmeter Test Method uses a calibrated precision engineered Gustavsson-Trichter with a 2.5 mm orifice, allowing the powder to flow freely under gravity while measuring the flow time and the mass of powder that passes through. This provides insight into how powders behave during dosing, filling, spreading, or sintering operations.

Experts rely on the Gustavsson-Durchflussmesser-Kit because it offers a repeatable, low‑complexity measurement that correlates strongly with particle morphology, surface roughness, moisture content, and internal friction. Powders with irregular shapes, high surface area, or poor lubrication typically show longer flow times or may not flow at all. The Gustavsson-Trichter is particularly sensitive to subtle differences in powder treatment, making it useful for quality control and batch comparison.

In addition to flow time, the method is often paired with an apparent density measurement using a standardized density cup. Together, these parameters help engineers predict how powders will behave in real‑world processes such as die filling, powder bed recoating, or compaction. Because the method is standardized including ISO 13517, results are comparable across laboratories and suppliers, supporting consistent material qualification and process optimization.
