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.

Abstract: One example provides an article. The article includes a container body. The article includes a lid covering the container body, the lid including a lid aperture to permit passage of a printing fluid into the container body. The article includes a lid manifold mounted to the lid. The lid manifold includes a lid manifold input port to be fluidly connected to and disconnected from a container manifold port of a separate printing system. The lid manifold includes a lid manifold output opening that is in the form of a needle having a length of less than or equal to about 6 mm and is fluidly connected to the lid aperture. The lid manifold includes a channel fluidly connecting the lid manifold input port and the lid manifold output opening.

Abstract: A fluid container orientation sensor is disclosed. The fluid container orientation sensor may comprise a first vibrational member having a first resonant behaviour and a second vibrational member having a second resonant behaviour. The first vibrational member may be disposed at a first depth within the fluid container. The second vibrational member may be disposed at a second depth within the fluid container A method and a print apparatus are also disclosed.
