FAST LOOP RESERVOIR

2.5
The fast -loop reservoir, required for online applications, allows continuous flow of the sample
from the sampling point. Inside the fast-loop reservoir the sample is at atmospheric pressure and
this allows the sample pump to provide the analyzer with a constant delivery of sample with no
overpressure. In addition, the fast-loop reservoir holds additional sample to avoid false alarms in
case of brief loss of sample as well as to remove air bubbles that may be present in the sample
line.

The stainless steel drain tubing maintains a constant water level inside the reservoir and
allows forproper sample circulation to avoid accumulation of suspended solids..

The sample flow should be adjusted to allow continuous sample overflow to waste
through the U-shaped stainless steel tube. Inside the reservoir a level sensor checks for
sample presence. If sample flow is lost, the level switch will place the analyzer in standby
mode. When sample flow resumes and level is detected in the reservoir, the analyzer will
start automatically with a new cycle.

Connect the cable from the fast-loop reservoir to the level switch connector on the right-
hand side of the instrument case, near the top.

3041 Silica Analyzer
In the case of dual stream units, there will be two separate
fast loop reservoirs, one for each of the sample streams.
