FLEXIM Results
• Flexim had installed 15 Dual Channel
meters through the site.
• All 8 Generator’s Supply and Return
lines were all measured simultaneously
Transducer Location
(supply)
• The average flow rate measured on
Generator supply lines was 2.3 Gpm
much less that the required 3.5 Gpm.

FLEXIM Results
Typical Results of Generators 1-7 during intermittent runs.
12
FLEXIM Results
Heavy aeration was also present in the supply line of Generator #8.
13
FLEXIM Results
Air bubbles at one point became visible through the glass Fuel Filter/separator.
This confirmed that the Flexim results were accurate.
14
FLEXIM Results
In the basement, Flexim meter revealed that the
first three pipes to the left were heavily
Aerated and most of the fuel flowed through the
4th pipe (to the right).
15
FLEXIM Results
� The main fuel line would provide
constant flow of fuel for 30 seconds
before it chocked out. The drop in
Gpm’s was displayed on the Flexim
meter.
