Abstract:
1. A method for measuring volume flow rate of liquid flowing into a container and/or volume of liquid, which has flowed into the container, which method comprises the steps of: enclosing a gas under a starting pressure in a predetermined starting volume in the container before liquid flows in; then allowing liquid to flow into the container to compress the enclosed gas to a gas volume dependent on the volume of liquid which has flowed into the container and to effect a rise of gas pressure of the gas in the container relative to the starting pressure dependent on the volume of liquid which has flowed in and on the volume flow rate of the inflowing liquid; measuring gas pressure in the container as a function of time; and determining, based on measured gas pressure, the volume of liquid which has flowed in up to a given time and/or the volume flow rate of inflowing liquid at the given time.
