These configurations may include a pump head, an actuator that penetrates into the pump head, a sealed region disposed about the actuator to form a fluid-free zone, and a fluid sensing unit coupled with the sealed region, the fluid sensing unit comprising a receptacle that is configured to retain fluid that transits from inside the sealed region.
