Abstract
A system, method, and apparatus for detecting at least one condition of interest relating to a tube, e.g. the presence of an air bubble. In some embodiments, the sensor includes antennas, a split-ring resonator, a frequency generator capable of generating frequencies in the microwave range, and a detection component. The detection component may estimate at least one parameter of received microwave energy in order to determine if a condition of interest exists.
