DETECTOR
| 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 |
0.831 gph for
leak rate of 3.0 gph.
0.066 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, fuel oil #4. |
| 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 45
gallons. |
| Waiting
Time |
None between
delivery and testing.
None between dispensing and testing for leak rate of 3.0 gph.
Minimum of 2 hours between dispensing and testing for leak rate of 0.1
gph. |
| Test
Period |
Response time is
20 seconds for leak rate of 3.0 gph.
Response time is 20 minutes for leak rate of 0.1 gph.
Test data are acquired and recorded by a permanently installed
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, 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. |
