Odorant Inlet Pressure Monitoring
For the fill valve to function correctly a pressure dif-
ferential between the Bulk Odorant Storage Tank and
the Expansion Tank, must be maintained. This differ-
ential should never be less than 0
.35 Bar
and typically
not more than 0
.69 Bar
. There are two alarms that
may be triggered from the Odorant Inlet Pressure
reading, a High Odorant Inlet Alarm, and a Low Odor-
ant Inlet Alarm.
