The research proposes a methodology of high-rate cavitation tests significantly decreasing testing period as well as increasing the accuracy of specifying a cavitation characteristic. To specify it, the tests without holding up consumption are conducted; however, at the pump inlet the rate to minimize pressure is increased. To decrease a test discrepancy, the data logging system is introduced. The research determines the high-rate pressure decreases without holding up consumption; it does not impact the accuracy to specify the cavitation characteristic and minimizes pump operation under the cavitation conditions diminishing erosive action. Automation significantly minimizes labour intensity during tests and improves the accuracy.
