摘要：
A liquid delivery system cap device is provided. In some embodiments, an example cap device includes a body defining a cavity configured to receive at least a portion of a liquid delivery device, a first sensor configured to output a first sensor signal indicative of a plunger of the liquid delivery device, a second sensor configured to output a second sensor signal indicative of a position, and a processor configured to detect a plunger of the liquid delivery device based on a variation in the sensor signal of the first sensor and to determine a corresponding position based on a sensor signal output by the second sensor.
