The sample recovery tank has two effluent
inlet ports. One inlet port is for effluent
from the Sample Conditioning Unit (Aquanot®),
while the other inlet port is for effluent
from the on-line analyzer.
The level sensor provides feedback to the pump
in the form of a low alarm and a high alarm.
As a precaution against tank overfill, the
Sample Recovery System can also generate a
high-high alarm signal that is detectable by
the on-line analyzer. The on-line analyzer
will respond by stopping the testing so that
effluent will not continue to enter the sample
recovery tank. An alarm signal will also be
sent to the control room
