Differential PQ / Fe Screen
Detects when large ferrous particles rise faster than spectrometric Fe.
Where to use
Detects when large ferrous particles rise faster than spectrometric Fe.
Methodology
Uses only submitted measurements and transparent deterministic formulas/rules. No model training or hidden ML logic is used.
Standards context
Console version
DifferentialPqIronDiscordance.exe input.csv output.json
CSV header: pq_index,fe_ppm,warning_ratio,critical_ratio
Limitations
The result is an engineering screen. Interpret it with the fresh-fluid baseline, laboratory method, OEM requirements and the asset-specific trend.
