Installing the Sample System
The analyzer is shipped complete with a Filterblock Assembly, Pressure
Regulator, and a Solenoid Valve. Unless specified, the Sample and Vent
Line Connection Fittings on the Filterblock Assembly are 1/4" Swagelok
®
tubing fittings.
Flow restrictors used to control the flow rate of the sample gas and bal-
ance the pressure drops within the sample system and Measuring Cell are
integrated within the sample system.
The Flow Restrictors must never be removed.
The Filterblock Assembly contains (2) Membrane Filters and a coalescing
filter to trap liquid entrainment, plus an additional Flow Restrictor to pro-
vide liquid drainage and a fast loop to the common Vent Line.
Disposal of the sample gas may be a vent to atmosphere or to an ap-
proved low pressure (<50 PSIG) flare header.
