Working Principle

Hall and Carney Funnel Methods

H-Flow is a simple, robust test setup measuring flow time through calibrated Hall and Carney funnel orifices.

⬇️
Hall Funnel (2.5 mm)
Standard funnel with 2.5 mm orifice, used for free-flowing metal powders.
⬇️
Carney Funnel (5.0 mm)
Funnel with 5.0 mm orifice for low-flow powders that do not pass the Hall funnel.
📋
ASTM B213 Compliance
The primary flowability standard for the powder metallurgy sector. Supplier certificate values can be verified directly in the laboratory.
📊
Result: s/50g Unit
Results are reported as the flow time of a 50 g sample, in seconds (s/50g).

Frequently Asked Questions

What You Wonder About

The Hall funnel has a 2.5 mm orifice and the Carney funnel a 5.0 mm orifice. Low-flow powders that do not pass the Hall funnel are tested with the Carney funnel.

The standard test uses a 50 g sample; the result is reported as flow time in s/50g.

Powders that do not pass the Hall funnel are tested with the wider 5.0 mm Carney funnel.

H-Flow measures flow rate in accordance with ASTM B213 and ISO 4490.

The set includes both Hall and Carney funnels; the appropriate funnel is selected according to the powder's flowability.
