Electrodes are integrated into a container design for fluid level detection in the container. The electrodes have a conductive surface, and an adhesive backing may be attached opposite the conductive surface to secure the electrodes to the container. Electrical contact to each conducting surface is made to a detection circuit to obtain a fluid level. A radio-frequency identification (RFID) tag may be incorporated onto the container along with the level detection circuit to record the container history, such as last used time event, net evaporation during storage, re-suspension performance after storage, number of agitation cycles, instrument serial number, date opened/accessed, and other desirable information. |
