ABSTRACT:
By means of a suction pump located at the outlet of the analyzer device and a combination of choke members connected in parallel in a row and respective low pressure controllers at the outlet of the gas analyzer and at the connection point of the series connection and parallel connection of the choke members, a constant sample flow through the analyzer is produced. Thus, even where there is a fluctuating measuring gas pressure and a variable flow resistance in the inlet part of the gas analyzer, the proportionality of the measuring signal to the concentration of the measuring component is ensured.
