Classification: CPC A  G | IPC A  G

Claim 0:
1. A sensor device for use with fluid flow systems, the sensor device comprising:
a heating element;
a first temperature sensor configured to generate first temperature data;, a second temperature sensor configured to generate second temperature data, wherein the heating element, the first temperature sensor, and the second temperature sensor are thermally coupled with a fluid flow system; and, a controller operably coupled with the heating element, the first temperature sensor, and the second temperature sensor, wherein the controller is configured to:
determine a first moving average for a first period of time based upon the first temperature data generated by the first temperature sensor during the first period of time;
determine a second moving average for the first period of time based upon the second temperature data generated by the second temperature sensor during the first period of time;
determine a first air presence parameter based upon a comparison between the first temperature data and the first moving average and a comparison between the second temperature data and the second moving average;
determine a second air presence parameter based upon a comparison between the first temperature data, the second temperature data, and one or more calibrated air thresholds;
determine a third air presence parameter based upon a comparison between a first temperature data entry and each second temperature data entry; and
detect a presence of an air bubble within the fluid flow system based upon the first air presence parameter, the second air presence parameter, and the third air presence parameter.
