Actual CSLD Test Problems Analyzed
ANALYSIS OF RATE TEST (IA52)
The average leak rate (AVLRTE) is -0.259. The average leak rate is uncompensated so excessive compensation is
not an issue. This leak rate is not excessively high so blender/pump sense issues are probably not involved.
The tank label is SUPER so most likely it is not manifolded.
The DATE is recent so results are up to date.
The maximum number of tests is 80 and because C1 = 79 there are more than enough tests.
SOLUTION
The float was stuck in the riser. A collar was installed on the probe to prevent recurrences of this problem.
CSLD PROBLEM 2 - MANIFOLDED TANKS 1 AND 2 ARE FAILING
Reports I201, I51, IA52, and I752 were collected for analysis.
