FE PETRO STP-MLD+G, STP-MLD+AG, STP-MLD+D and STP-MLD+BD Pipeline Leak Detector
(for Rigid, Flexible, or Hybrid Combination of Rigid and Flexible Pipelines)

Automatic Mechanical Line Leak Detector

Certification Leak rate of 3.0 gph with PD = 100% and PFA = 0%.
Leak Threshold 3.0 gph.
A pipeline system should not be declared tight if the test result indicates a loss that equals or exceeds this threshold.
Applicability Gasoline, gasoline-alcohol mixtures, aviation fuel, fuel oil #4, solvents, diesel, 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.
*NWGLDE Listings apply to leak detection functionality only and not material compatibility - see "Disclaimer".
Specification System tests pressurized rigid and flexible pipelines.
Tests are conducted at operating pressure.
Pipeline Capacity Maximum for rigid system is 165.1 gallons.
Maximum for flexible system is 109.8 gallons
Maximum combined capacity is 274.9 gallons, not to exceed the above individual capacity limitations for rigid or flexible pipelines.
Waiting Time None between delivery and testing.
None between dispensing and testing.
Test Period Response time is less than 2 minutes
System Features Permanent installation on pipeline.
Automatic testing of pipeline. Preset threshold.
Single test to determine if pipeline is leaking.
Restricted flow to dispenser 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.

Evaluations determined that the STP-MLD+D and STP-MLD+BD Pipeline Leak Detectors will operate correctly with a range of diesel from 100% diesel to 100% Ultrazol 9888, OTR 8843G, and OTR 8332G.
