Abstract:
A method of filling a receptacle with a net weight substance by means of a filler member disposed to introduce the substance into the receptacle while the receptacle is being carried by a force sensor, the method comprising at least one cycle comprising the steps of:placing the receptacle on the force sensor; commanding the filler member to start a flow of the substance; repeatedly measuring the time for which the substance has been flowing since the start-of-flow command was issued; measuring a value of a signal supplied by the force sensor at least at first and second separate measurement instants; calculating a mean flow rate of the substance over the time interval between the measurement instants; making at least one computed evaluation of a filling time on the basis of the calculated mean flow rate and a reference weight; and commanding the flow of substance to stop when the flow time of the substance is equal to the evaluated filling time.
