ABSTRACT:
A system for sampling flue gases for a Klaus process controller by periodically capturing flue gas in a sample chamber with one side closed and the other side open, closing the other side, and only thereafter exposing the other side to a carrier fluid having a constant rate of flow. The carrier fluid and flue gas thus mix and are subsequently scrubbed and fed to the balance of the controller apparatus. The sample chamber is opened and closed by metal bellows operated valves selectively provided with positive and negative (vacuum) interior pressures in a certain sequence.
