Abstract
A sensor operable to sense a characteristic of a fluid. The sensor includes a sensing area, a filter, and a transducer. The sensing area is configured to contain the fluid. The filter covers the sensing area. The filter is configured to allow a liquid portion of the fluid to enter the sensing area and substantially prohibit a gas portion of the fluid to enter the sensing area. The transducer is operable to output a pulse of sound through the liquid portion of the fluid contained within the sensing area, receive the reflected pulse of sound, and output a characteristic of the fluid based on the received pulse of sound.
