Abstract
In some examples, an apparatus includes a pressure sensor, and a controller to determine, based on pressure data from the pressure sensor, an amount of time to depressurize a fluid supply from a first pressure to a second pressure, and determine a level of a fluid in the fluid supply based on the amount of time to depressurize the fluid supply from the first pressure to the second pressure.
Claims18
A printing system comprising:
- a pressure sensor;
- and
- a controller to:
- determine, based on pressure data from the pressure sensor, an amount of time to depressurize a fluid supply from a first pressure to a second pressure, and
- determine a level of a fluid in the fluid supply based on the amount of time to depressurize the fluid supply from the first pressure to the second pressure during a print operation of the printing system that prints fluid from the fluid supply to a target.

A printing system comprising:
- a mounting structure to mount a fluid supply;
- and
- a controller to:
- receive pressure data from a pressure sensor, the pressure data relating to depressurization of the fluid supply;
- determine a level of a fluid in the fluid supply based on an amount of time to depressurize the fluid supply from a first pressure to a second pressure during a print operation of the printing system that prints fluid from the fluid supply to a target.
2 more elements
A method comprising:
- pressurizing a fluid supply of a printing system to a first pressure;
- measuring, by a pressure sensor, pressure data relating to depressurization of the fluid supply from the first pressure;
- and
- determining, by a controller, a level of a fluid in the fluid supply based on an amount of time to depressurize the fluid supply from the first pressure to a second pressure different from the first pressure during a print operation of the printing system that prints fluid from the fluid supply to a target.
