ABSTRACT:
A sample of slurry is withdrawn continuously from a pressure pipe through which the slurry flows by a diluting sample-extractor mounted on the pipe. Dilution water is added continuously to the extractor to mix with the withdrawn sample to provide dilute slurry, and the quality of the dilute slurry is evaluated by passing it through a viewing window chamber and taking periodic photographs of the dilute slurry passing through such viewing window chamber.
