Abstract: Generally, example systems and methods for measuring aeration level of a liquid may involve measuring the pressure at two points in the liquid reservoir. The aeration level of the liquid in the liquid reservoir may be calculated based on the pressure differential between the two points in the liquid reservoir. Optionally, the aeration level of the liquid may be compared to a threshold value of the liquid aeration level, and a machine action may be commanded if the aeration level exceeds the threshold value. Example machine actions may include warning the operator. In addition, data relating to the level of aeration of the liquid may be stored, along with other machine parameters, and the data correlated for analysis and machine diagnostics.

Abstract: An exhaust treatment system of a power source system includes a filter having an inlet and an outlet and a first exhaust line located between the filter and a power source of the power source system. The exhaust treatment system further includes an ultrasonic energy generating device coupled to the filter. In addition, the exhaust treatment system includes a second exhaust line coupled downstream of the filter.
