Line Integrity Probe and Submersible Pump Controller
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 | 2.0 gph for leak rate of 3.0 gph. 0.06 gph for leak rate of 0.1 gph. A pipeline system should not be declared tight if the test result indicates a loss or gain 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 129 gallons. |
| Waiting Time | None between delivery and testing. None between dispensing and testing. |
| Test Period | Response time is 1 minute for leak rate of 3.0 gph. Response time is 1 hour, 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 the microprocessor. |
| System Features | Permanent installation on pipeline. Automatic testing of pipeline. Preset threshold. Single test to determine if pipeline is leaking. Pump shutdown, 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. |
