(originally listed as Gilbarco Environmental Products and later as Marconi Commerce Systems)

EMC Environmental Management Console with Line Leak Detector,
Series PA0263000060X (Same as Veeder-Root Series 8484)


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 1.88 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. 
Other liquids may be tested after consultation with the manufacturer.
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 98.4 gallons.
Waiting Time None between delivery and testing. 
Minimum of 16 minutes between dispensing and testing for leak rate of 3.0 gph. 
Minimum of 45 minutes to 1 hour between dispensing and testing for leak rate of 0.2 gph. 
Minimum of 2 hours, 30 minutes between dispensing and testing for leak rate of 0.1 gph.
Test Period Response time is 28.8 seconds for leak rate of 3.0 gph. 
Response time is 32 to 48 minutes for leak rate of 0.2 gph. 
Response time is 18 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. 
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.
