Liquid sampling apparatus

摘要

Disclosed is an apparatus for obtaining a continuous substantially particle-free sample of a liquid comprising a rotatable disc disposed beneath a conduit from which a stream of liquid to be sampled is discharged onto a portion of the disc and a drive motor for rotating the disc at a speed sufficient to form a bed of liquid about the disc periphery. A continuous sample of the liquid is removed by a blade positioned to engage the bead adjacent an edge portion of the disc at a point along the disc periphery opposite the portion wetted by the stream so that any solid particles which may be present in the liquid are carried off in the stream flowing from the disc before reaching the blade.
