Line Leak Detector Model LLP2
Automatic Electronic Line Leak Detector
Certification | Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%. Leak rate of 0.1 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 | 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. |
Comments | Control Engineers no longer manufactures this equipment. The company and rights for this product were sold to Veeder-Root. *For product support information, contact Veeder-Root. |
