| Certification |
Leak rate of 3.0 gph at 10 psi* with PD = 100%
and PFA = 0%.
Leak rate of 0.2 gph at operating pressure with PD = 100%
and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure*
with PD = 100% and PFA = 0%.
*Since leak rate varies as a function of
pressure, this leak rate and pressure were certified using an equivalent
leak rate and pressure, in accordance with an acceptable protocol. |
| Leak
Threshold |
1.5 gph for leak
rate of 3.0 gph.
0.1 gph for leak rate of 0.2 gph.
0.05 gph for leak
rate of 0.1 gph.
A pipeline system should not be declared tight if the
test result indicates a loss that equals or exceeds this threshold. |
| Applicability |
Gasoline, diesel,
aviation fuel, #4 and #6 fuel oil, solvents, used oil, ethanol blends up
through E100, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100
meeting ASTM D6751. |
|
Specification |
System tests
pressurized rigid, flexible, and combinations of rigid and flexible
pipelines.
Tests are conducted at operating pressure.
System will
not function with a mechanical line leak detector installed in the pipeline. |
|
Pipeline Capacity |
For 3.0 gph
(hourly), 0.2 gph (monthly) and 0.1 gph (annual) leak rate test:
Maximum
of 124 gallons flexible or semi-rigid pipe
Maximum of 559 gallons for
combination (flex, semi-rigid, rigid) pipelines with a minimum bulk modulus
of 21,987 psi. |
|
Waiting Time |
None between
delivery and testing.
None between dispensing and testing. |
| Test
Period |
Response time is
13 to 14 minutes (average test time of 14 minutes) for a leak rate of 3.0
gph.
Response time is 5 to 6 hours (average test time of 5.5 hours) for
a leak rate of 0.2 gph.
Response time is 5 to 15 hours (average test
time of 14.25 hours) for leak rate of 0.1 gph.
Test data are acquired
and recorded by a microprocessor.
Calculations are automatically
performed by the microprocessor. |

System Features |
Maglink LX
console used in this evaluation with Dover ELLD.
Permanent installation
on pipeline.
Automatic testing of pipeline.
Preset threshold.
Pump shutdown (optional), message display and alarm activation if leak is
declared. |
| Calibration |
System must be
checked annually and, if necessary, calibrated in accordance with
manufacturer's instructions. |
| Comments |
System was
evaluated on a pipeline consisting of rigid and flexible piping, and the
resulting combined bulk modulus was determined by physical measurement at
evaluator’s facility.
During initial setup, it is necessary to program
the console by activating the consoles “learn” mode in order for the console
to gather data on the pipeline with a Dover supplied leak orifice installed.
Once the “learn” mode is finished, the system is ready to monitor the
pipeline and will not need to be re-programmed unless the line
characteristics change. |
