ABSTRACT:
Fluids such as saline solution that are disposed in containers such as contact lens packages can be detected by directing ultrasonic energy at the container and receiving a return reflection of the ultrasonic energy. The ultrasonic energy and the return reflection can propagate through a shroud that substantially isolates the ultrasonic energy and the return reflection from air currents.
