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
|
2.0
gph for leak rate of 3.0 gph.
0.1 gph for leak rate of 0.2 gph.
0.047 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, methanol, and methanol blends, ethanol blends up through E100, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751*.
Other liquids with known coefficients of expansion and density may be tested after consultation with the manufacturer.
*NWGLDE Listings apply to leak detection functionality only and not material compatibility - see "Disclaimer".

|
Maximum
of 55.1 gallons.
|
|
Waiting
Time
|
None

|
Test
Period
|
Response
time is 2 minutes for leak rate of 3.0 gph.
Response time is 10 minutes to 3 hours for leak rate of
0.2 gph.
Response time is 2 hours, 30 minutes to 3 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
|
Permanent
installation on pipeline.
Automatic testing of pipeline. Preset threshold.
Single test to determine if pipeline is leaking.
Recording and display of day, date, and time of conclusive
test.
Pump shutdown, message display, 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.

|
Comments
|
PPM
4000 is a stand alone automatic electronic line leak detector.
RLM 9000 is a combination of RLM 5000 automatic tank gauge
and PPM 4000 automatic electronic line leak detector.
