Abstract
A metering device for a machine for making a liquid preparation includes a liquid reservoir for storing a fluid and for feeding, via an inlet line, at least one pump arranged to force the fluid to pass, in the liquid and/or vapour state, through at least one doser including at least one ingredient, in order to make the preparation, and to dispense the preparation to an outlet line. The metering device also includes means for continuously measuring the mass of the reservoir and of its contents, and control means interfaced with the continuous measurement means and arranged to monitor the total mass as a function of time, and to instantaneously calculate the mass of the preparation already dispensed, to adapt the duration of operation of the pump to ensure that the exact quantity of preparation required is dispensed, and/or to trigger the shutdown of the pump if it is found to be running dry.
