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 1):
An apparatus for dispensing or aspirating a predetermined volume of liquid fluid in a container, said container comprising a chamber having an internal volume V and at least an opening for granting communication with the chamber, the apparatus being configured to be connectable to the container about the opening thereof and comprising:\n at least one connecting port configured to connect the apparatus to the container about the opening in a gas and liquid tight manner; a dispensing unit configured to dispense and/or aspirate a predetermined volume of liquid fluid from the chamber, said dispensing unit comprising a dispensing or aspirating channel having a first end in fluidic communication with a liquid containing part of the chamber and a second end opposite the first end extending outside the container for dispensing or aspirating a metered amount of liquid fluid, and liquid flow controlling means being arranged on the dispensing or aspirating channel to open/close said channel respectively; and a metering unit configured to meter a flow of compressible gas injected or released from the chamber, said dispensing unit and metering unit being in fluidic communication with said chamber through said at least one connecting port, wherein the metering unit comprises a gas feedthrough channel having a first end in fluidic communication with 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 flow {dot over (V)} within the gas feedthrough channel and to calculate the container fill level V gas  and dispensed amount of liquid after aspiration or dispensing thereof from the chamber by integration of the gas flow {dot over (V)} value.
