- This metering device 500 comprises a reservoir 1 of liquid for storing a fluid and for supplying, through an inlet channel 2, at least one pump 3.
- This pump 3 is arranged to force the passage of the fluid, in the liquid and/or vapor state, through at least one dispenser 4 arranged to contain at least one ingredient, for making the preparation, and to deliver the preparation to at least one outlet channel 5.
- the metering device 500 comprises means for continuously measuring the mass of the contents of tank 1, or else the mass of tank 1 and its contents. Indeed, it is possible to carry out a preliminary taring of the tank. Any measurement set out below can of course be made in relative or absolute terms.
- the metering device 500 comprises control means 10, which are interfaced with these continuous measurement means, and which are arranged to track the total mass as a function of time. These control means 10 are also arranged to perform the instantaneous calculation of the mass already delivered of the liquid preparation, to adapt the operating time of the pump 3 to ensure the delivery of the exact quantity of preparation required, and / or to trigger stopping the pump 3 during a finding of operation empty, to avoid any phenomenon of cavitation and degradation of the pump.
- the mass measurement is advantageous for detecting any empty operation of the pump, and stopping the cycle in time. It is therefore not necessary to equip the machine with a flow meter or the like, to protect the pump from running dry.
- the means for continuously measuring the mass of the tank 1 and its contents, or else only the contents of the tank 1 comprise means 20 for weighing the tank 1 and its contents, which are interfaced with control means 10 that comprises the metering device 500, and which are arranged to determine the initial mass of the reservoir 1 and its contents, or else of the contents of the reservoir 1 alone, from the start of a manufacturing cycle of the preparation.

For example, for the same coffee pod, a setting allows the user to select a particular type of drink: espresso, lungho, ristretto, or other.
- These control means 10 are further arranged to actuate the operation of the pump 3 during the start of the cycle, to continuously control the weighing of the instantaneous mass of the tank 1 and its contents, or else of the contents of the tank 1 alone, and to deliver the required amount of the liquid preparation to the outlet channel 5.
- the weighing means 20 can incorporate different types of sensors: strain gauge, piezoelectric, pressure-sensitive film, or any other sensor capable of measuring mass, pressure, or force. Such a sensor can be arranged between the body of the machine and the reservoir 1, to allow real-time calculation of the volume of liquid present in the reservoir, the tare of which is known or is easy to memorize.
- control means 10 are arranged to be activated for the launch of the manufacturing cycle, either by an action by a user on a control panel 11 interfaced with the control means 10, or else by a command carried out by an automated system interfaced with the control means 10.
- control means 10 are arranged to detect an unexpected filling of the tank 1 during the operation of the pump 3. More particularly, the control means 10 are arranged to stop the pump 3 in the event of finding of increase in the instantaneous mass of tank 1 and its content, or else of the content of tank 1 alone.
- control means 10 are arranged so that, in the event of a finding of an increase in the instantaneous mass of the reservoir 1 and its contents, or else of the contents of the reservoir 1 alone, wait for the stabilization of the mass, and restart the supply cycle of the pump 3 until the complete delivery of the required quantity of the preparation at least one outlet channel 5, and stopping the operation of the pump 3 when the comparison indicates that the entire mass of liquid to be delivered was delivered to pump 3.
- control means 10 are arranged to measure the value of the initial mass of the reservoir 1 and its contents, or else of the contents of the reservoir 1 alone, at the moment of the start of a manufacturing cycle. , and, in the event of a finding of constancy or reduction in the instantaneous mass of the tank 1 and its contents, or else of the contents of the tank 1 alone, continuously carry out the comparison between on the one hand the value of the mass of liquid at deliver and on the other hand the value of the difference between the initial mass and the instantaneous mass, and stop the operation of pump 3 when the comparison indicates that the entire mass of liquid to be delivered has been delivered to pump 3.
- control means 10 are arranged so that, in the event of an increase in the instantaneous mass of the tank 1 and its contents, or else of the contents of the tank 1 alone, recording in the storage means 12 , which the control means 10 comprise, a first intermediate value which is the value of the instantaneous mass of the reservoir 1 and of its contents, or else of the contents of the reservoir 1 alone, at the moment when the instantaneous mass increases.
- steering means 10 are arranged to follow the weighing means 20 until a finding of stabilization of the instantaneous mass at a second intermediate mass, to calculate the difference between the second intermediate mass and the first intermediate mass, and to calculate a new mass of upstream which is the total of the initial mass and the difference, and to restart the operation of the pump 3 and continuously carry out the comparison between on the one hand the value of the mass of liquid to be delivered and on the other hand the value of the difference between the upstream mass and the instantaneous mass, and to stop the operation of pump 3 when the comparison indicates that the entire mass of liquid to be delivered has been delivered to pump 3.
- control means 10 are arranged to compare the theoretical calibration curve for monitoring the mass of the tank as a function of time, with the real curve during the execution of a cycle.
- a difference threshold between these two curves it is possible to program a difference threshold between these two curves to trigger an alert. This alert allows, depending on the programming performed, for example and not limited to:
- the metering device 500 comprises closure means 13 arranged to prohibit the filling of the tank 1 during the launch of the manufacturing cycle and until the moment when the entire mass of liquid to be delivered has been delivered to pump 3.
- control means 10 comprise means 12 for storing, for each type of liquid preparation based on a pair formed by a fluid and an ingredient, the correlation between the quantity of fluid to be provided and the amount of liquid preparation delivered.
- the metering device 500 comprises, downstream of the outlet channel 5, at least one receptacle 6, which is arranged to receive at least one container intended to receive the liquid preparation, and comprises, in a variant, secondary weighing means 30, which are interfaced with the control means 10, and are arranged for measuring the tare consisting of the at least one container, and for continuously monitoring the quantity of liquid preparation delivered. It is then possible to continuously and repetitively measure the mass of the container and the quantity of dispensed preparation that it contains, until the desired quantity is reached.
- the control means 10 are then arranged to stop the pump 3 in time, during an approach report of the desired quantity downstream by these secondary weighing means 30, to avoid any overflow.
- the metering device 500 comprises, at the level of the output channel 5, at least one output flowmeter 60, interfaced with the control means 10 and a clock 50 that the control means 10 comprise, for the continuous monitoring of the quantity of the liquid preparation delivered by the outlet channel 5.
- the metering device 500 comprises, between the pump 3 and the at least one metering device 4, at least one boiler 70 to heat and/or vaporize the fluid before it passes through the at least one metering device 4.
- control means 10 include a long-term monitoring function of a machine 1000 incorporating such a metering device 500.
- the control then makes it possible to monitor the ratio between on the one hand an initial duration, measured during learning or first use, and corresponding to the supply of the mass of liquid to be delivered to provide the ideal volume, and on the other hand the real time required to provide the same mass after several months/year of functions to introduce, for a particular preparation, and to compare in real time this ratio with a pre-determined threshold value of this ratio, threshold which once exceeded gives rise when a maintenance message from the machine 1000 or from the metering device 500 is displayed, to trigger descaling or another maintenance operation.
- this control of the duration of the manufacturing cycle of a liquid preparation does not have the effect of managing the operation of the machine 1000 or of the metering device 500 for the manufacture of a liquid preparation, but of allowing a maintenance monitoring of the equipment during its lifetime.
- this machine 1000 works perfectly when purchased, with an initial volume of water required of 100% for a certain cycle duration, after several months of use and depending on the hardness of the water, the same volume of 100% may take much longer to deliver.
- the invention makes it possible to avoid managing the unit cycle time for the manufacture of a liquid preparation, and this provision for integrating a threshold into the control process makes it possible to avoid the case where the volume which passes through the pump 3, the doser 4, and the possible boiler 70, becomes so weak that the pump 3 operates much longer than reasonable, which weakens it and risks leading to its destruction if a maintenance operation is not triggered on time.
- control means 10 comprise a control panel 11, or are interfaced with a control panel 11, and include a learning cycle arranged to allow a user to manually prepare a particular liquid preparation, and to select the quantity of the liquid preparation, and/or the nature of the liquid preparation, and/or the density or the aromatic density of the liquid preparation, and/or the nature of the at least one ingredient, and/or the nature of the fluid, and to trigger automatic storage of the operating parameters of the dosing device 500 for this particular liquid preparation, and the correlation between the quantity of the liquid preparation at the outlet channel 5 and the mass of liquid to be delivered upstream of the pump 3.
- the invention also relates to a machine 1000 for manufacturing a liquid preparation, comprising at least one such metering device 500.
- this machine 1000 is arranged for the instantaneous manufacture of liquid food preparation based on at least one powdery or concentrated or freeze-dried ingredient, and at least one fluid, and the at least one doser 4 consists by a percolator filter, or a sachet, or a capsule, or a cartridge or a pod and comprises a dose of at least one ingredient.
