This paper comes in continuation of former studies on finite-difference modeling for pipelines dynamics with a purpose of model-based fault detection. The finite-difference model is here revisited, and enhanced with extremal instrumentation modeling. It is then emphasized how such a model can indeed be useful for fault detection, in particular including instrumentation faults in addition to leaks for instance.
