ABSTRACT:
In order to determine the proportion of particles of less than a predetermined size in a fluid suspension, the fluid suspension is placed in a vessel (1) and is thoroughly mixed therein by mixing means (36,37). A sample of suspension is then withdrawn from a predetermined level within the vessel (1) by means of a sampling tube (9) and is transferred by way of a flexible tube (22) to a container (15). The particle concentration of this sample is then monitored by passing x-rays from a source (17) through the container (15) and detecting the emerging x-rays with a detector (18). The sample is then drained from the container (15). After allowing the suspension in the vessel (1) to settle for a time sufficient to enable particles of said predetermined size to sink from the surface of the suspension to said predetermined level within the vessel (1) according to Stokes' law, a further sample of suspension is withdrawn from said predetermined level and transferred to the container (15). The x-ray monitoring process is then repeated with this further sample. The complete testing cycle takes place automatically under the control of a control system coupled to a plurality of motors (such as 6) and valves (25, 28, 30, 34).
