AUTOMATIC ELECTRONIC LINE LEAK DETECTOR

Certification	Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%. Leak rate of 0.1 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. 0.06 gph for leak rate of 0.1 gph. A pipeline system should not be declared tight if the test result indicates a loss or gain 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 129 gallons.
Waiting Time	None between delivery and testing. None between dispensing and testing.
Test Period	Response time is 1 minute for leak rate of 3.0 gph. Response time is 1 hour, 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 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	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.
