Vaporless Manufacturing
Vaporless LD-2100 or PLC-5000 with 98LD-2000PLC (for Rigid and Flexible Pipelines)
Automatic Electronic Line Leak Detector
| Certification | Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%. Leak rate of 0.2 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. 0.136 gph for leak rate of 0.2 gph. 0.068 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 flexible, fiberglass and steel pipelines. Tests are conducted at operating pressure. |
| Pipeline Capacity | Maximum of 172 gallons for rigid pipelines. Maximum of 39.5 gallons for flexible pipelines. |
| Waiting Time | None between delivery and testing. None between dispensing and testing. |
| Test Period | Response time is less than 8 minutes for leak rate of 3.0 gph. Response time is 1 hour, 48 minutes to 10 hours, 54 minutes for leak rates of 0.2 and 0.1 gph. |
| System Features | Permanent installation on pipeline. Automatic testing of pipeline. Preset threshold. Single test to determine if pipeline is leaking. LD-2100 is a stand alone system. PLC-5000 must be coupled with the 98LD-2000. 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. |
