2.3 Unpacking (cont.)
Remove the mounting studs at the bottom of the enclosure. Using two people, lift the Aurora H2O from the bottom of
the enclosure and from the top of the enclosure where the analyzer electronics is located. A typical Aurora H2O
weighs approximately 100 pounds (45 kg). Use a proper lifting technique to avoid injury.
Check all the received components and record the model numbers and serial numbers for your records. If anything
is missing, contact BH immediately.
2.4 Choosing A Site for Installation
You should have discussed environmental and installation factors with a BH 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 or plastic tubing at all costs, as water molecules will interact
with the tubing, 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 on page 3 .
