The disclosure is of a device (10) for indicating a plurality of data relating to the condition of fluid dispensations remaining in a container for holding, and dispensing metered quantities of the fluid. The device sequentially displays the time elapsed since the most recent dispensation, the number of fluid dispensations remaining in the container (16), and the number of dispensations made during the previous twenty-four hours. In one embodiment, a foam spring is included to closely match the pressure required to signal that a dispensation has occurred with the pressure required to make the dispensation, thereby minimizing false counts, and ensuring that each dispensation is included in the count. The foam spring (42) also provides a hermetic seal to the microelectronic means (40). The microelectronic means (40) is mounted on a glass sheet, and is hermetically sealed thereto. |
