AS-300 Hall Flowmeter and Bulk Density Apparatus for Free-flowing Metallic Powders

The AS-300 Hall Flowmeter (Funnel) supplied by AimSizer Scientific determines flow rate and apparent density of free-flowing metallic powders and other fine powders in a variety of particle size distributions with calibrated a hall flowmeter funnel as per international standards:

  • ASTM B213 Standard Test Method for Flow Rate of Metal Powders
  • ASTM B212 Standard Test Method for Apparent Density of Free Flowing Metal Powders Using the Hall Flowmeter Funnel
  • ISO 4490 Metallic powders - Determination of flow rate by means of a calibrated funnel (Hall Flowmeter)
  • MPIF No.4 Std. 04—Apparent Density of Free-Flowing Metal Powders Using the Hall Apparatus
  • ISO No. 3923-1 Metallic powders - Determination of apparent density - Part 1 Funnel method
  • MPIF No.3

The AS-300 also determines the apparent density of non-free-flowing powers with a Carney funnel according to international standards.
