  "account": "The engineering summary outlines a system design for physical AI that addresses issues with radar tank gauge readings at a fuel terminal in Pakistan. The system involves surveying the signal health of three Modbus RTU loops feeding data to a centralized gauging host. To ensure accurate readings, the design measures signal health before purchasing any equipment, installing booster installations inside explosion-proof junction boxes, and setting the count of tanks based on the survey results.\n\nThe system models 15 objects, including fuel tanks, radar tank gauges, communication loops, Modbus boosters, junction boxes, gauge readings, data quality events, central inventory pictures, loop wiring as-built, service orders, warranty records, OEM authorization letters, HSE work permits, instrumentation technicians, and location engineers. In the event of a distorted reading from one tank, a query is sent through the loop, booster, as-built document, assigned technician, and work permit, tracing the issue back to its source.\n\nThe design emphasizes deterministic checks with no reliance on learned models, ensuring that each check is a clear rule that an instrument engineer can follow. Every data quality event moves through a defined process, from open to acknowledged to resolved, and requires a named person to sign off on each transition. The entire system runs as containers on the operator's own site application server, projecting a central inventory picture over the gauging host without replacing it.\n\nNo upfront cost is associated with the design, as the field equipment falls within the original requirement's supply scope and is priced by OEM quotation against the survey. The full design, figures, and object model are available in the paper, which can be cited using DOI 10.5281/zenodo.23157967. The system was designed using CodeNinja Praxis, a platform for designing physical AI systems, and can be imported into Hyper Ontology for further development.",
