AUTOMATIC ELECTRONIC LINE LEAK
DETECTOR
| 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 |
1.88 gph for leak
rate of 3.0 gph.
0.17 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. |
| Specification |
System tests
pressurized fiberglass and steel pipelines.
Tests are conducted at operating pressure.
System will not function with a mechanical line leak detector installed in
the pipeline. |
| Pipeline
Capacity |
Maximum of 98.4
gallons. |
| Waiting
Time |
None between
delivery and testing.
Minimum of 16 minutes between dispensing and testing for leak rate of 3.0
gph.
Minimum of 45 minutes to 1 hour between dispensing and testing for leak
rate of 0.2 gph.
Minimum of 2 hours, 30 minutes between dispensing and testing for leak
rate of 0.1 gph. |
| Test
Period |
Response time is
28.8 seconds for leak rate of 3.0 gph.
Response time is 32 to 48 minutes for leak rate of 0.2 gph.
Response time is 18 minutes 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. 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. |
