Fluid aeration sensor and method of operating the same

Abstract

A fluid sensing system including a first transducer, a second transducer, a filter, and a controller. The first transducer is configured to output a first sound wave through a first fluid in a first measurement channel. The second transducer is configured to output a second sound wave through a second fluid in a second measurement channel. The filter is configured to substantially prevent aeration in the second fluid contained within the second measurement channel. The controller is configured to determine a first characteristic of the first sound wave, and determine a second characteristic of the second sound wave. The controller is further configured to determine a percentage of aeration by volume within the first fluid based on the first characteristic and second characteristic, and output the percentage of aeration by volume within the first fluid.
