Abstract
An apparatus for the measurement of the cavitation or ebullition rate comprises an accelerometric transducer in contact with the liquid under cavitation or boiling and a filter and amplifier connected in cascade and having an input electrically connected to the transducer for providing on the output of the amplifier a signal containing information about cavitation or ebullition. This signal is then processed and displayed by two separate circuits. The first threshold circuit is connected to the output of the amplifier for eliminating signals having a value lower than a preset threshold value, a flash follower connected to the threshold circuit, and a counter and display connected to the flash follower. The display is adapted to provide a count of events in the signal sensed by the accelerometric transducer which surpass the preset threshold value. The second circuit includes an r.m.s. converter for providing the r.m.s. value of the signal obtained on the output of the amplifier. An integrator is connected to the converter for obaining at its output the average value of the r.m.s. value. Read-out circuit indicates the average value of the r.m.s.
