TS-LLD Line Leak Detector



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 1.5 gph for leak rate of 3.0 gph. 
0.1 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 fuels, fuel oil #4.
Specification System tests pressurized fiberglass and steel pipelines. 
Tests are conducted at operating pressure.
Pipeline Capacity Maximum of 163 gallons.
Waiting Time None between delivery and testing. 
None between dispensing and testing for leak rate of 3.0 gph and 0.2 gph. 
Minimum of 8 hours between dispensing and testing for leak rate of 0.1 gph.
Test Period Response time is 3 minutes for leak rate of 3.0 gph. 
Response time is 50 minutes to 8 hours for leak rate of 0.2 gph. 
Response time is 40 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, numerical "fail" code display and LED alarm light 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 For test using leak rate of 0.2 gph only:
After 28 days have elapsed since the last passing monthly line leak test, system shuts off the submersible pump.
System display will flash number of days since the last passing test. Operator may reset button to enable dispensing for a 24 hour period. 
This procedure may be used for a maximum of 4 days. 
After 32 days have elapsed since last monthly test, system will disable dispensing and automatically initiate a test, and system will not authorize dispensing until a test is passed or system is serviced.
