Note:
The Aurora RM is not equipped with alarm relays. Alarm status can be obtained via Modbus, or an Analog
Output can be configured as an alarm signal (see "Selecting an Output Type" on page 45 of the Aurora H2O
User Manual).
4. Making sample gas connections
The Aurora RM has a basic sample handling system with ¼” compression bulkhead fittings provided for connecting
sample inlet and outlet as shown in Figure 6. Appropriate safety precautions shall be taken to vent process gas to
avoid the build-up of hazardous concentrations of flammable, toxic, or inert gases. For safe and effective operation,
both the gas inlet and vent connections should be leak checked as ambient air leaks into the sample flow can lead
to erroneous moisture readings.
As shown in Figure 1 the front panel has a 0–5 l/min (air) rotameter that indicates sample flow and includes a needle
valve in the bottom to control flow as required. Although the Aurora RM reading is insensitive to flow, it is
recommended the sample flow be set toward the center of this scale.
CAUTION!
Please ensure the gas sample introduced into the Aurora RM is regulated down to
under 100 PSIA and is filtered (i.e., free of liquid and particulate contamination) as
the sample system in the Aurora RM does not include any pressure regulation
and/or membrane filters.
CAUTION!
The maximum sample inlet pressure is 7 bar (102 PSIA).
