The secondary ta

Analysis of Rate Table (IA51)
Rate table shows large negative rates and the rates are inconsistent. This is an indication that CSLD is not
detecting dispensing soon enough. If the leak test had stopped after dispensing began, the result would have
been a negative rate.
The solution for this type of problem is pump sensing. BUT this site has pump sensing with line leak devices. The
problem in this example was that the pump wiring to the line leak devices was correct, but the line leak tank
assignments were incorrect.
Solution
Reassign Tanks 4 and 1 to their installed line leak devices (in this example, Line 1 [Reg] to Tank 1, Line 2 is
correctly assigned to Tank 3, but Line 3 [Premium] should be assigned to Tank 4).
CSLD PROBLEM 3 - INCREASE RATE WARNING FOR MANIFOLDED TANKS 2 AND 3
Reports IA52 and IA53 were collected for analysis.
