[QUOTE="Baluncore, post: 5489246, member: 447632"] Welcome to PF. Is this a ferrofluid or are the particles permanent magnets ? [URL]https://en.wikipedia.org/wiki/Ferrofluid[/URL] Do the particles aggregate in the liquid and then begin to fall through the liquid ? How many aggregations do you have moving through the liquid at one time ? You might consider moving the liquid at a rate that holds the particles in a steady position. Over time the flow rate would give the velocity. It might be possible to measure bulk position of aggregates in a column with an LVDT made from three coils wound around the column.
