UNIT FOR MEASURING THE SETTLING VELOCITY OF PARTICLES IN SUSPENSION IN A FLUID AND DEVICE COMPRISING AT LEAST SAID UNIT AND AN AUTOMATIC SAMPLER

摘要

A unit for measuring the falling speed of particles in suspension in a fluid comprises a sealed container having an open compartment containing fluid, and a sealed compartment, and, in the sealed compartment, at least three electromagnetic radiation emitters distributed along a longitudinal axis of the open compartment and oriented according to a radiation axis crossing the open compartment at different heights along the longitudinal axis, an equal number of receivers distributed along the longitudinal axis, each receiver placed in the radiation axis of a corresponding emitter, and a system for acquiring data connected to the receivers which is used to obtain the falling speed of the particles and the change of same as a function of the height in the open compartment and as a function of time, said change quantifying the flocculation of the particles.
