2.4.7
The BX-RES (see in Figure 2-14) is an optical reservoir sensor used in the tank's
interstitial space containing a brine solution. A rise in the level of the reservoir liquid
is indicative of outside water getting in due to a breach in high ground water
conditions, or product due to an inner wall breach in high ground water conditions. A
drop in the liquid level can be caused by a breach in the inner or outer wall.
When installing sensor, ensure that the brine level is within proper proportion to the
amount of product in the tank. Obtain a brine chart from your tank manufacturer for
purposes of this installation.
