Abstract
A method and apparatus is disclosed for measuring the volume of fluid in a variable volume vessel.
Claims28
A method for measuring the volume of fluid in a variable volume vessel, the method comprising the steps of:
- recording data representing the temperature and pressure of gas from the vessel;
- modifying the volume of gas in the vessel by a measured volume;
- selecting a plurality of data points from the recorded temperature and pressure data from a region in the pressure data representing substantially constant volume of the vessel;
- calculating the volume of gas in the vessel from the measured volume and the temperature and pressure data for the selected data points;
- and
- outputting the calculated gas volume.
