TLS 350, 350PC, 350R, 350 RPC, 350Plus, LLD-300, Red Jacket ProMax Line Leak Detector, with Series 8494 Wireless Pressurized Line Leak Detector (WPLLD)

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 2.5 gph for leak rate of 3.0 gph.
0.17 gph for leak rate of 0.2 gph.
0.09 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.
*NWGLDE Listings apply to leak detection functionality only and not material compatibility - see Disclaimer.
Specification System tests pressurized fiberglass and steel 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 100 gallons.
Waiting Time None between delivery and testing.
None between dispensing and testing for leak rate of 3.0 gph.
Minimum of 45 minutes between dispensing and testing for leak rate of 0.2 gph.
Minimum of 2 hours between dispensing and testing for leak rate of 0.1 gph.
Test Period Response time is less than 1 minute for leak rate of 3.0 gph.
Response time is 30 to 45 minutes for leak rate of 0.2 gph.
Response time is 32 to 48 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.
Total vertical rise of pipeline must not exceed 11 feet above transducer.
Transmits leak detection test data to console through submersible pump power wiring. 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 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.
