Because LEF readings require no soil contact, the technique works where contact-based surveys can’t: paved areas, frozen ground, rocky terrain, and congested facility piping. It’s an efficient screening tool for prioritizing where close interval or voltage gradient surveys should focus.

LEF testing services include:

• Current attenuation measurement along the pipeline
• Coating condition screening and anomaly prioritization
• Location of current drains and unintended metallic contacts
• Pipeline locating and depth verification
• Data analysis by certified corrosion professionals
• Integration with CIS, DCVG, and ACVG survey programs
