Line Leak Detector
Model LLP2



Leak rate of 3.0 gph at 10 psi* 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. 0.05 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.
Specification System tests pressurized fiberglass and steel pipelines. 
Tests are conducted at operating pressure.
Pipeline Capacity Maximum of 89 gallons.
Waiting Time None between delivery and testing. 
None between dispensing and testing for leak rate of 3.0 gph. 
Minimum of 15 minutes between dispensing and testing for leak rate of 0.1 gph.
Test Period Response time is approximately 10 seconds for leak rate of 3.0 gph. 
Minimum of 30 minutes for leak rate of 0.1 gph. 
Test data are acquired and recorded by a permanently installed microprocessor. 
Calculations are automatically performed by a microprocessor.
System Features Permanent installation on pipeline. 
Automatic testing of pipeline. Preset threshold. 
Single test to determine if pipeline is leaking. 
Pump shutdown, indicator light and alarm activation if leak is declared.
Calibration System must be checked annually and, if necessary, calibrated in accordance with manufacturer's instructions.
Comments Control Engineers no longer manufactures this equipment.
The company and rights for this product were sold to Veeder-Root.
