LineTite Pipeline Leak Monitor
(for Flexible Pipelines)


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. 
0.062 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 flexible pipelines.
Tests are conducted at operating pressure.
System will not function with a mechanical line leak detector installed on the pipeline.
Pipeline Capacity Maximum of 49.6 gallons.
Waiting Time None between delivery and testing. 
None between dispensing and testing.
Test Period Response time is 1 to 6 minutes for leak rate of 3.0 gph. 
Response time is 2 hours, 18 minutes to 5 hours 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.
