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.
