Abstract
Abstract A line of continuously flowing material is reciprocately swung over a sample funnel to obtain a sample of the material. The sample is fed into a sample feeding pipe and from there to a through flow cell. The sample of material in the sample feeding pipe is automatically held at a substantially constant level, thus keeping the sample flow through the cell constant. The cell is positioned at least as high as the sample level for continuously maintaining a reduced pressure inside the cell.

Claim 1
Independent Claim
124 words
A continuously operating apparatus for sampling liquids or slurries by passing a sample through a through-flow cell for analysis, comprising: a line for continuously carrying a flow of material and means for taking a representative sample of the material; a sample funnel for collecting the sample; a sample feeding pipe for receiving the collected sample and passing the sample on to the through-flow cell; means for automatically keeping the sample in the feeding pipe at a substantially constant level and for keeping the sample flow rate to the through-flow cell substantially constant by controlling the sample-taking means; said through-flow cell being positioned at least as high as the sample level in the feeding pipe for continuously maintaining a reduced pressure inside the throughflow cell.
