Companies like meteringtech.com have “self learning” software (ours is called TRACKER analysis module of DYNAMAT) that will self learn a profile of consumption from high frequency interval data (AMR) and continuously compares current consumption with the self learned target, alarming if excessive consumption is detected. We can home in on the “night line” hours as a further refinement.
This TRACKER module has saved a fortune in energy and water consumption. At RAF Lossiemouth it detected a major water main burst (cast iron) which was undetected at the surface but excavating a large hole (soil ladened water passing straight to drain) – could have been catastrophic to aircraft if had got undetected.
The problem with roll out of this type of simple low cost technology is interfacing to the water company meters!
