HOW IT WORKS

01
Read sensors
Pressure and flow are sampled at fixed pipeline intervals.
02
Build baseline
Expected pressure drop is estimated for normal demand.
03
Score residuals
Sudden pressure loss plus flow imbalance creates an anomaly score.
04
Localise segment
The first sharp residual change identifies the likely pipe section.
