The ELG includes a radar-based obstruction detection algorithm stored in a memory coupled thereto. A processor implementing the obstruction detection algorithm identifies at least a first feature in the first echo curve to provide at least one suspected obstruction along with its position (first feature position). A second echo curve is generated from a second reflected signal when the material is at a second level. A third echo curve is generated from a third reflected signal when the material is at a third level. The suspected obstruction at the first feature position is stored in the memory as a verified obstruction with its first feature position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Marking tank obstructions using an electronic level gauge","description":"An obstruction marking method includes generating a first echo curve using an electronic level gauge (ELG) coupled to a tank from a first reflected signal (echo signal) received when a material in the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9618612","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
