2.3.2 Extractive Installation
For extractive installations we recommend our sample sys-
tem ESS, which may be equipped with a variety of features,
such as: isolation valve, coalescing or particulate filter,
pressure regulator, calibration sample injection or extraction
port, pressure gauge, flow meter, weatherproof enclosure.
Refer to the ESS literature for more information.
If the resources to make your own sample system are avail-
able, the following two diagrams may be used as a guideline
to configure a simple system.
