Abstract:
An apparatus and method for precisely dispensing liquid fluid from a container are disclosed. The apparatus comprises a metering unit having a gas feedthrough channel with a first end extending in a gas containing part of the chamber and a second end opposite the first end extending outside the chamber, the metering unit further comprising a flow sensing assembly configured to measure a gas pressure differential Δp and/or gas flow V{dot over ( )} within the gas feedthrough channel and to introduce or release a determined volume of gas in the chamber to dispense a controlled volume of liquid from the chamber.

Claim (Index 12):
A method for dispensing or aspirating a predetermined volume of liquid, comprising:\n providing a container comprising a chamber having an internal volume V and an opening for granting communication with the chamber, said chamber comprising a volume V 1  of a liquid and a volume V 2  of a compressible gas, such that, when said chamber is closed V=V 1 +V 2 ; connecting an apparatus to the opening of the chamber by a connecting port such that a first end of a gas feedthrough channel extends in a gas containing part of the chamber and a second end of the gas feedthrough channel extends outside the chamber, and such that a first end of a dispensing or aspirating channel extends in the liquid contained in the chamber and a second end of the dispensing or aspirating channel extends outside the container; activating or opening the dispensing or aspirating channel and deactivating or closing the dispensing or aspirating channel after a predetermined time; metering a gas flow {dot over (V)} within the gas feedthrough channel by a flow sensing assembly, said gas flow being induced from the pressure source or ambient pressure into the chamber; and calculating container fill level V gas  and dispensed amount of liquid by integration of the gas flow {dot over (V)} value measured with the flow sensing assembly.
