<p>A vessel fill level is qualitatively determined and indicated by a device having a base and a vessel-supporting member that is resiliency suspended inwardly from and above the base. The base has an annular body with at least three stanchions, symmetrically spaced around the annular body, as well as a plurality of radially- inwardly-extending arms. Each stanchion has a vertical slot and each of the arms meet at an axial base member. The vessel support has a plurality of radially-outwardly extending arms and is adapted to support the vessel. A distal end of each of the arms is received and retained in one of the vertical slots, where a spring connects the arm to the base. Means for distinguishing at least two levels of vertical separation between the base and the vessel-supporting member provides a qualitative signal to a display that may be on the base or remote to the device.</p> |
