Abstract

A method includes determining particle size distribution (PSD) in a fluid flow line based on a range of sizes for at least one particle in the fluid flow line and duration of reflection of a laser beam from the at least one particle. The laser beam is focused from a laser beam instrument in direct contact with the fluid low line.
