Scott Volumeter [repack] -

: A large brass funnel often equipped with a 16-mesh screen to break up agglomerates, followed by a smaller conical funnel to direct the flow.

To address this, George D. Scott (often associated with the Paint Research Institute) developed an instrument in the mid-20th century that became standardized as the (ASTM B329, ISO 3923-2). The device introduces a controlled, gravity-fed “raining” of powder through a series of angled glass plates or baffles, breaking agglomerates and ensuring a repeatable loose packing state before the powder falls into a calibrated receiving cup. scott volumeter

In , the Scott Volumeter is often used alongside Hall flowmeter (ASTM B213) to certify metal powders. A powder with too low an apparent density (< 40% of true density) may cause “spatter” or layer voids; too high may indicate excessive fines or agglomerates. : A large brass funnel often equipped with
