⚠ Participant type(s) not in COPI vocabulary
PhysicalQuantityValueLocalIndication
Participant types are hand-authored in
copi-vocab, not produced by the pipeline.
Replace each with an existing vocab type, redirect it to a BFO / IOF-Core class in copi-iri-map.tsv,
or add it to copi-vocab.ttl first.
This entry cannot be saved as validated until then.
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
The gauge converts the measured physical quantity into a local readable indication using only the energy inherent in the measured quantity, distinguishing it from transmitters and indicators that require auxiliary power.
