Hello, I am looking for a way to measure the dosage of a powder (made of metallic particles (ferromagnetic) that are 6 microns large) in a liquid solution that is kerozene. When mixed with the liquid a suspension is obtained that takes about one hour for the powder to settle down. Once settled down, the powder covers around 5% of the liquid volume. I am looking for a technique to measure the dosage of the powder in the liquid (its percentage in the liquid volume.) I tried U tube liquid variation but it was not conclusive... Any idea? Thanks.
