AS-300 Hall Flow meter includes AS-300A Automatic Hall Flowmeter and AS-300M Manual Hall flowmeter, both conform to all current international standards
ASTM B213 Standard Test Method for Flow Rate of Metal Powders
ISO 4490 Metallic powders – Determination of flow rate by means of a calibrated funnel (Hall Flowmeter)
-MPIF No.3
ASTM B212 Standard Test Method for Apparent Density of Free Flowing Metal Powders Using the Hall Flowmeter Funnel
-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

In addition AS-300 determines Apparent Density of non-free-flowing powers with Carney Funnel according to International Standards
ASTM B417 Standard Test Method for Apparent Density of Non-Free-Flowing Metal Powders Using the Carney Funnel
-MPIF No.28
ISO No.3923-1

Principle

Flow Rate
AS-300 Hall Flowmeter Funnel determines the flow rate by measuring the time taken by 50 gram of a metal powder to flow through a calibrated hall flowmeter funnel/orifice of standardized dimensions(0.1 inch/2.5 mm) according to International Standards.
Apparent Density of free-flowing powders
AS-300 Hall Flowmeter determines the apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from a hall flowmeter funnel orifice Diameter 0.1 inch/2.5 mm into a specified density cup of definite volume(25 cm³) under controlled conditions. The mass of powder per unit volume (the ratio between the mass and the volume) is recorded and reported as apparent density.
Apparent Density of non-free-flowing powders
AS-300 determines the apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from a Carney funnel diameter 0.2 inch/5.0 mm into a specified density cup of definite volume(25 cm³) under controlled conditions. The mass of powder per unit volume (the ratio between the mass and the volume) is recorded and reported as apparent density.
