Overview

AS-300 Hall Flowmeter (Funnel) /Hall Flow Meter (Funnel) determines both Flow Rate and Apparent Density. It is applicable to both free-flowing metallic powders and other fine powders testing. The testing is performed with a 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
As for non-free-flowing powers, AimSizer recommends a Carney Funnel (orifice Dia.5.0 mm) 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

In addition to traditional manual type hall flowmeter, AimSizer debuts its New Automatic Electric Hall Flowmeter AS-300A No.033698. Such Hall Flowmeter uses a patented internal sensor system to sense the powder flow, from beginning to the end. And a timer real-timely records and shows the flow time accurately. User simply add sample and the following procedures are completely automatic. With such device user needn't to worry about any human factors which bring negative effect to the manual test results all the time. A satisfying and repeatitive results is at hand any time after a simple sample adding. AS-300A is world's first automatic hall flowmeter.

Principle
- Measure Flow Rate by a Hall Flow Meter Funnel
AS-300 Hall Flowmeter Funnel determines hall flow rate. The test is operated by measuring the time taken by 50 gram of a metal powder to flow through a hall flowmeter funnel. The funnel is calibrated on the orifice(0.1 inch/2.5mm) by standardized Chinese Emery according to International Standards ASTM B213/ISO 4490 in order to get 40±0.5 second flow rate.
- Measure Apparent Density of free-flowing powders by a Hall Flow Meter Funnel
AS-300 determines apparent density of free-flowing powders. 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. The powders flow into a specified density cup of calibrated volume(25cc) 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.
- Measure Apparent Density of non-free-flowing powders by a Carney Funnel
AS-300 determines apparent density of non-free-flowing powders. 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. Carney funnel is not calibrated and for purpose of measuring the apparent density only.
Applications
Powder metallurgy, metallic powders, food powders, cement powders, plastic powders, rubber powders, ceramic powders, pharmaceutical powders,foundry,casting,metalworking, etc.
