1. A filling machine for filling containers with a pourable product, the filling machine comprising:

  • a product tank containing the pourable product and a first gas maintained at a first pressure value;

    at least one dosing tank containing a second gas and configured to measure out a given volume of the pourable product to be delivered to a container through a first valve;

    a fluidic line connecting the at least one dosing tank to the product tank through a second valve;

    a first pressurizing device configured to selectively pressurize the second gas in the at least one dosing tank to a second pressure value, that is lower than the first pressure value, when the first and second valves are both in respective closed configurations and the at least one dosing tank does not contain a substantial amount of pourable product;

    a sensor configured to detect pressure of the second gas in the at least one dosing tank; and

    a controller configured to;

    set the second valve in an open configuration after the at least one dosing tank has been pressurized to the second pressure value, in order to allow the pourable product to flow from the product tank to the at least one dosing tank under the action of the pressure difference therebetween; and

    set the second valve in the closed configuration as the pressure detected by the sensor in the at least one dosing tank, during flow of the pourable product into the at least one dosing tank, reaches a third pressure value corresponding to a predetermined volume of the pourable product in the dosing tank.
