Abstract: A fluid characteristic sensing device has a projection. The fluid characteristic sensing device receives current pulses and directs the received current pulses through the projection. The received and directed current pulses enable determination of a resistance of the projection and a rate of change of temperature.

Abstract: In some examples, a container assembly includes a first body to supply a printing composition, the first body comprising a first port, and the container assembly includes a second body to store a reserve printing composition, the second body comprising a second port. An interconnect has a storage position to fluidically isolate the first body from the second body, and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body. The interconnect in the storage position has a first orientation to fluidically isolate the first port from the second port, and the interconnect in the use position has a second orientation rotated with respect to the first orientation to fluidically connect the first port to the second port.

Abstract: An example apparatus includes a housing including a first chamber and a second chamber, the housing defining a first port to fluidly couple the first chamber to a printer, the housing including a second port to fluidly couple the first chamber and the second chamber; a bladder disposed in the first chamber, the bladder being inflatable to increase a pressure within the first chamber; and a regulator to regulate fluid flow from the second chamber to the first chamber and to deter fluid flow from the first chamber to the second chamber.
