Abstract (en)

Exemplary embodiments are disclosed of controllers (e.g., control panels, etc.) configured to be operable for detecting cavitation using torque load and/or instantaneous fuel consumption. In exemplary embodiments, a controller is configured to be operable for monitoring at least one of engine torque load and/or engine instantaneous fuel consumption for fluctuation (e.g., significant drop/downward fluctuation in average magnitude and/or erratic, noisy, fluctuating data, etc.) indicative of pump cavitation, thereby enabling the controller to be operable for alerting to indications of pump cavitation when fluctuation of the monitored engine torque load and/or engine instantaneous fuel consumption indicate pump cavitation.
