An upper boundary of the chamber includes a seal and a lower boundary of the chamber includes a liquid surface and determining a volume of the chamber at a first time. The method further includes determining the volume of the chamber includes measuring, using a pressure gauge, a first pressure within the chamber, changing an amount of a gas in the chamber, and measuring, using the pressure gauge, a second pressure within the chamber. The method further includes determining a first volume of gas within the chamber based on the first and second pressure measurements and the change in the amount of gas, and determining a first fluid level based on the first volume of the chamber.
