A method, probe (14) and system for detecting presence of cavitation in a liquid and measuring cavitation density and intensity of a specific locale in the fluid. A first cavitation void (11-1 ) and associated energy perturbation, produced in a first liquid (L1), moves within the first liquid (L1) and is received at a very thin plate (13), which separates the first liquid (L1) from a second liquid (L2) and is part of a light-proof chamber (15) containing the second liquid (L2). An energy perturbation in the first liquid (L1) is received at the thin plate (13) and produces at least one cavitation void or associated energy perturbation (11-1 ) in the second liquid (L2); and the energy perturbation in the second liquid (L2) is eventually converted into an electromagnetic signal. This signal is received by a photomultiplier (19) and converted to an electronic signal that indicates the presence of cavitation. The system can distinguish between cavitation voids produced at one location and/or time interval and voids produced at another location and/or another time interval.
