AS-300 Hall Flowmeter

Overview
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 funnel according to 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) ● ASTM B212 Standard Test Method for Apparent Density of Free Flowing Metal Powders Using the Hall Flowmeter Funnel ● ISO No. 3923-1 Metallic powders - Determination of apparent density - Part 1 Funnel method ● MPIF No.4 Std. 04—Apparent Density of Free-Flowing Metal Powders Using the Hall Apparatus ● MPIF No.3
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 ● Metallic powders - Determination of apparent density - Part 1 Funnel method ● MPIF No.28

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 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 apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from aCarney Funnel (a similar size of metallic funnel, the difference between a hall flow funnel and carney funnel is the orifice diameter, hall flow funnel 2.5mm and carney 5.0mm) 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. Carney funnel is not calibrated and only for purpose of measuring the apparent density only.
