Patent ID: 8250902

Claim:
A system for measuring aeration of a liquid in a machine, comprising: an ultrasonic transmitter configured to engage a liquid channel; an ultrasonic receiver configured to engage the liquid channel; wherein the ultrasonic receiver receives a reflection of an ultrasonic wave corresponding to an ultrasonic wave sent by the ultrasonic transmitter; and a controller operably connected to the ultrasonic receiver, wherein the controller is configured to calculate the aeration of the liquid channel based upon the signal from the ultrasonic receiver and command a machine action if the aeration of the liquid channel exceeds a threshold value of liquid aeration; wherein the machine is selected from a group including a motor vehicle and a construction machine; and wherein the controller is further configured to divide the width of the liquid channel into a plurality of divisions, and to calculate the aeration of the liquid channel based upon the signal received corresponding to one of the plurality of divisions.
