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 11):
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 ; providing an apparatus according to  claim 1 ; connecting the apparatus to the opening of the chamber by the connecting port such that a first end of the gas feedthrough channel extends in a gas containing part of the chamber and the second end of the gas feedthrough channel extends outside the chamber, and such that the first end of the dispensing or aspirating channel extends in the liquid contained in the chamber and the second end of the dispensing or aspirating channel extends outside the container; activating or opening liquid flow controlling means in the dispensing or aspirating channel and deactivating or closing it after a predetermined time; metering a gas flow {dot over (V)} within the gas feedthrough channel by a flow sensing assembly comprised in the metering unit said gas flow being induced from the pressure source or ambient pressure into the chamber; and calculating container fill level V g as  and dispensed amount of liquid by integration of the gas flow {dot over (V)} value measured with the flow sensing assembly.
