AS-300 Hall Flowmeter (Funnel) /Hall Flow Meter (Funnel) determines both Flow Rate and Apparent Density of free-flowing metallic powders as well as other fine powders in various particle size distributions with calibrated hall flowmeter. 
It meets 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/2.5mm) according to International Standards. 
–Apparent Density of 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 hall flowmeter funnel orifice Diameter 0.1 inch/2.5mm into a specified density cup of definite volume(25cm3) 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/5.0mm into a specified density cup of definite volume(25cm3) 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.
