scada

What is it that you are actually trying to achieve? How long time period and how many values are we talking about?

The issue sounds quite interesting, but I highly doubt there would be any ready solutions for this kind of thing.

yes it is interesting..i am working on a project pipeline leak detection ..the project containing ultrasonic flow meter and plc ..i need to monitor any change for flow value and pressue ..the historical trend will show this but i need to make an alarm on changing time or specific variation time ..can scada do it ?
 
You are fingerprinting. That's a tough nut to crack. Sounds like you need to watch Ramp (or decay) Rate or 2 parameters and match that to your known "fingerprint" of a bad condition.
