Figure 6.21: Layout of the gas connections
Each gas inlet consists of the coupling (a 1/8" Swagelok pipe fitting) and an adapter
with an internal 2 filter.

pipe is used as a flame arrester and must not be reduced in size. It must be more than
25 cm (19") in length and its maximum internal diameter may be 0.015".

Right-hand sideIt is possible to measure up to 5 different
gases in sequence.
Left-hand side, first connection
Used to maintain measurement accuracy.
Left-hand side, second connection
For transporting the measurement gas inside the device;
waste gas is released into the housing.
Left-hand side, third connection The unmeasured sample
gas is released at ambient pressure.
Left-hand side, penultimate connection
Second carrier gas only needed to analyse biogas or
hydrogen in natural gas. In standard applications this
connection is not used and closed without piping inside
Left-hand side last connection
Flushing or bypass gas is released at a high flow rate.
Inside the device, the gas connections are each soldered (at
