Abstract

Automatic sampler for waste water comprises a pipe arranged to allow utilisation of the loss of load for distributing the samples, without using any additional energy source. The pipe extends spirally, with its loops disposed in vertical planes and alternating with discharge openings which may be directed downwardly, to the left or right and in a horizontal or oblique plane. The air outlet pipes for evacuating the receptacles have their upper ends disposed at a higher level that the main feed pipe.
