2.4 Choosing a site for installation
You should have discussed environmental and installation
factors with a Panametrics sales, application or service
engineer by the time you receive the analyzer.
Before installing the analyzer, read the guidelines below on
installation recommendations:
1. Choose an installation site for the
Aurora H2O analyzer as
close to the actual sample point (sample take-off point)
as possible, to minimize transport time to the analyzer.
2. Avoid unnecessarily long lengths of sample transport
tubing to minimize transport time to the analyzer.
3. Avoid dead-legs in the sample transport tubing to
minimize the possibility of liquid build-up.
4. Use stainless steel tubing. Avoid using copper tubing, as
the water molecule has greater absorption capabilities
for copper compared to stainless steel. Avoid rubber
tubing at all costs, as water molecules interact with the
rubber, and ambient moisture can permeate through
the tube wall into the sample gas.
5. Mount the Aurora H2O analyzer at grade, or at a location
that is easily accessible for maintenance (on a platform
or other structure).
6. Be sure that the ambient temperature is at least 10°C
higher than the maximum dew/frost point temperature
you expect to measure. This will ensure that you will not
have liquid condensation in the sample transport line
nor in the Aurora H2O . Heat tracing the sample line will
aid in elevating the sample temperature above the dew
point. An optional heater installed within the enclosure
is also available.
A typical Aurora H2O system for monitoring moisture off
a natural gas pipeline is shown in Figure 8 below.
