I know this is an academic excercise that only uses pressure but I find it interesting.
Now I've not tried this solutionmyself because we use devices that monitor the current and voltage to detect this very thing, but I would think that with enough resolution, there would be enough change in current from normal to detect the motor responding to the potential causes of cavitation. Or for that matter anything outside the pump curve.
I don't understand how suction pressure by itself could detect cavitation if it stayed above atmo. Low suction pressure would tell you that cavitation was possible, but not that it was happening unless the pump curve and service curves were somehow factored in.
