2.3.4 Process Connections
The process is connected through 600# ANSI RF flanges (other sizes available by request) at the top and
bottom of the analyzer. The process flow inlet should be at the bottom of the analyzer with the outlet at the top.
This prevents entrapment of any bubbles in the sample cell of the analyzer. A pump and sample probe may be
necessary to ensure that a representative sample of the process flows through the analyzer. The sample flow
should be more than 4 liters per minute (1 gallon per minute) through the analyzer to ensure representative
sample temperatures. The maximum sample flow rate through the analyzer is 208 liters per minute (45 gallons
per minute).
A thermal pressure relief valve is recommended in the plumbing between any shut valves to the analyzer. In the
unlikely event that the pressure exceeds the maximum specified (35 bar or 508 psig), the pressure relief valve
should open until the pressure falls below 508 psig.
