Extract every tag number, ISA 5.1 symbol, and instrument identifier from P&IDs with classification accuracy above 99%. Automated tag register generation for EPC handover.
Pre-trained on the complete ISA 5.1 symbol set. Recognizes control valves, instruments, actuators, and safety devices with classification accuracy above 99%.
Parses tag prefixes, functional identification letters, loop numbers, and suffix codes per ISA 5.1 conventions. Flags non-standard tags for review.
Generate complete tag registers with tag number, description, P&ID reference, loop assignment, and safety classification — ready for handover.
Tags appearing on multiple P&IDs are consolidated with revision tracking and positional context from each drawing.
Generate tag registers for EPC handover packages
Validate tag consistency across P&ID sets
Build instrument loop diagrams from extracted tag data
Create tag-to-document traceability matrices
Pathnovo recognizes the full ISA 5.1 symbol set including flow instruments, temperature instruments, pressure instruments, level instruments, control valves, safety valves, actuators, transmitters, and all standard modifier symbols.
Yes. While ISA 5.1 is the primary training standard, our models also handle DIN, BS, and company-specific tag conventions. Non-standard tags are flagged for manual review.
Pathnovo uses vision models specifically trained on the ISA 5.1 instrument identification standard. The models recognize symbol shapes, functional identification letters, tag number formats, and connection patterns. Training data includes 200,000+ engineering drawings spanning five decades of P&ID conventions, including hand-drawn, CAD-generated, and intelligent P&IDs.
