Abstract
In an example, a fluid level sensor comprises a vibrational paddle wherein an edge of the vibrational paddle comprises a fluid surface contact point having a peaked profile.
Claims15
A fluid level sensor comprising a vibrational paddle wherein an edge of the vibrational paddle comprises a fluid surface contact point having a peaked profile.
A replaceable print apparatus component comprising:
- a fluid container;
- and
- a fluid level sensor disposed within the fluid container comprising first and second vibrational limbs, wherein the first and second limbs extend in different directions, are disposed at different fluid depths within the container and are associated with respective first and second resonant behaviors.
A print agent container comprising:
- a fluid reservoir;
- and
- first and second resonator elements disposed within the fluid reservoir at different fluid depths and which extend in different directions, wherein the first resonator element exhibits resonant behavior when fluid is at a first depth in the reservoir and second resonator element exhibits resonant behavior when fluid is at a second depth in the reservoir, and the first and second resonator elements have a common mounting point.
