vEEDER-ROOT
Series 8590 DPLLD with 8600 Series System (Veeder-Root TLS-450)
(for Rigid, Semi-Rigid and/or Flexible Pipelines)
AUTOMATIC ELECTRONIC LINE LEAK DETECTOR
Certification
Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.2 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 fuel, ethanol blends up through E100, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751*.
Other liquids with known coefficients of expansion and density may be tested after consultation with the manufacturer.
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
For 3.0 gph (hourly) leak rate test and 0.2 gph (monthly):
Maximum of 425.84 gallons for rigid pipelines.
Maximum of 109.84 gallons for flexible pipelines.
Maximum of 643 gallons for semi-rigid pipelines.
Maximum of 1178.68 gallons for combination piping systems.
For 0.1 gph (annual) leak rate test:
Maximum of 165.08 gallons for rigid pipelines.
Maximum of 109.84 gallons for flexible pipelines.
Maximum of 267.84 gallons for combination piping systems.
Waiting
Time
None between delivery and testing.
Minimum between dispensing and testing.
Test
Period
Response time is 1 to 5 minutes for leak rate of 3.0 gph.
Response time is 48 minutes to 270 minutes for leak rate of 0.2 gph.
Response time is 48 minutes to 489 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 Failures
8600 Series console used in this evaluation with Series 8590 DPLLD.
Permanent installation on pipeline.
Automatic testing of pipeline.
Preset threshold.
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
Comments
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.
The bulk modulus of the piping system in which the device is installed can be calculated so that the software can be programmed to monitor various configurations of rigid/flexible combination piping systems at the facility.
