TLS-350, 350PC, 350R, 350RPC, 350Plus, Red Jacket ProMax Line Leak Detector, Series 8475 VLLD



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.
0.079 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.

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 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 158 gallons.
Waiting Time None between delivery and testing.
Minimum between dispensing and testing depends on volume of product and temperature gradient which is determined by system's computer.
Test Period Response time is 14 seconds for leak rate of 3.0 gph.
Response time is 6 minutes for leak rate of 0.2 gph.
Response time is 14 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.

If pump side leak testing is required, total vertical rise or pipeline must not exceed 8 feet above VLLD Controller.
Single test to determine if pipeline is leaking.
Pump shutdown, 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.
