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

1.5 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, ethanol blends up through E100, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751. 

Specification

System tests pressurized rigid, flexible, and combinations of rigid and flexible 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 119.4 gallons.

Waiting Time

None between delivery and testing.
None between dispensing and testing for leak rate of 3.0 gph.
Minimum of 4 minutes to 1 hour, 9 minutes between dispensing and testing for leak rate of 0.2 gph.
Minimum of 1 to 4 hours between dispensing and testing for leak rate of 0.1 gph.

Test Period

Response time is 1 to 6 minutes for leak rate of 3.0 gph.
Response time is 40 minutes to 227 minutes for leak rate of 0.2 gph.
Response time is 45 minutes to 333 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

TLS 350 console can only be used with Series 8484 PLLD.

TLS 450 console can only be used with Series 8590 DPLLD.

When using Red Jacket BIG-FLO Submersible Pump Models P100H1, P200H1, P200H3, P300H3, P500H3, the PLLD only performs 3.0 gph testing and not precision (0.2 and 0.1 gph) testing.

{USER DEFINED} pipe type must be selected under the PLLD setup to allow precision (0.2 and 0.1 gph) testing with Red Jacket BIG-FLO Submersible Pump Models:  MAXXUM MXP300, MAXXUM MXP500.

Total vertical rise of pipeline must not exceed 11 feet above transducer.

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.
System was evaluated on a pipeline consisting of rigid and flexible piping, and the resulting combined bulk modulus was determined by physical measurement at evaluator’s facility.
To use this system, a measurement of bulk modulus must be made at the owner's facility so that the software can be programmed to deal with the specific characteristics of the piping system at the facility.
