SS500/SS2000 Analyzer
4–8 4900002285 rev. B 3-25-20
3. Attach the supply line to the sample inlet and set the sample flow
rate by adjusting the pressure of the supply to 30-40 PSIG.
4. Adjust the rotameter for a cell flow of 1-1.5 SCFH.
If a test gas is used, nitrogen will show as 1 SCFH-AIR on the gauge.
Refer to Figure 4–4 for a bypass flow diagram if alternate settings
are required.
5. Open the rotameter by one-half turn to set the bypass flow to
approximately 0.45 SLPM-AIR for a methane or light natural gas
sample.
Do not exceed 60 PSIG at the sample inlet.
The analyzer must always
be operated with some gas flow in the
bypass (needle valve open) or the membrane separator will not
drain separated liquids. If liquids enter the cell, shut down the
analyzer and
remove the liquids. Refer to “Service Contact” on
page B-22
for information on removing liquids.
