Certification
|
Leak
rate of 3.0 gph at 10 psi* 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
|
1.88
gph for leak rate of 3.0 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.
|
|
Specification
|
System
tests pressurized fiberglass and steel pipelines.
Tests are conducted at operating pressure.
|
|
Pipeline
Capacity
|
Maximum
of 89 gallons.
|
|
Waiting
Time
|
None
between delivery and testing.
None between dispensing and testing for leak rate of 3.0
gph.
Minimum of 15 minutes between dispensing and testing for
leak rate of 0.1 gph.
|
|
Test
Period
|
Response
time is approximately 10 seconds for leak rate of 3.0
gph.
Minimum of 30 minutes for leak rate of 0.1 gph.
Test data are acquired and recorded by a permanently installed
microprocessor.
Calculations are automatically performed by a microprocessor.
|
|
System
Features
|
Permanent
installation on pipeline.
Automatic testing of pipeline. Preset threshold.
Single test to determine if pipeline is leaking.
Pump shutdown, indicator light and alarm activation if
leak is declared.
|
|
Calibration
|
Equipment
must be checked annually for capability of detecting a
line leak of 3.0 gph and, if necessary, calibrated in
accordance with manufacturer's instructions.
