Abstract
Embodiments herein relate to systems for detecting air bubbles in fluids. In an embodiment, a fluid system aeration detector is included having an optical air bubble sensor. The optical air bubble sensor can include a light source, a light detector, and a sensor controller. The sensor controller can be in signal communication with the light detector and can be configured to detect air bubbles based on the signals received from the light detector. The sensor controller can further be configured to estimate an amount of aeration of a fluid based on the detected air bubbles. Other embodiments are also included herein.
