Sensing cavitation?
(OP)
Is there any way to measure or sense cavitation in pumps?

RE: Sensing cavitation?
Sometimes you can hear cavitation (sounds like rocks being pumped) and sometimes you can't.
Check for pitting on the tips of the impeller and within the pump's nozzle area.
I'm sure others can offer more advice.

To answer the post, it has been mentioned, check NPSH against curve etc and then if you are trying to avoid operating at these points, put some kind of protection device onto the motor based on flow rates etc - not sure of your reasoning or application, but there are many things to assist you...

No higher frequencies, say from bubble collapse? I think that is what BigInch was alluding to...
Does your statement hold for multi-bladed turbine pumps, regardless of number of blades? What about multi-cylinder piston pumps?
