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

EMC, EMC-PC, EMC Enhanced, EMC-PC Enhanced,
LMS Environmental Management Consoles with Line Leak Detector,
PA0263000100X (Same as Veeder-Root Series 8494),
PA0277000060X (Same as Veeder-Root Series 8494)


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. 
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 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. 
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.
