Preferred Embodiment of the Invention

First, the installation described in the main patent P201431943 is described in a general and merely illustrative manner, so that the figures can be correctly interpreted to locate and relate the new elements that are part of the present addition within the installation (10) of said main patent.

Specifically, Figure 1 shows a beverage dispensing installation (10) comprising a first (3a) and a second (3b) beverage dispensing lines, where each of them (3a, 3b) is connected to a tank (2 ) or beverage storage barrel with a beverage dispenser (9).

Likewise, the installation (10) comprises a discharge pump (4) and a foam detector (6) connected to each beverage dispensing line (3a, 3b), as well as a gas bottle (16) connected to the lines of dispensing beverage (3a, 3b) to add gas to the beverage contained in both tanks (2).

On the other hand, the gas bottle (16) has a pressure sensor (5) configured to generate a pressure signal (SpBG (3a, 3b)) indicative of said gas pressure contained in the gas bottle (16) .

The discharge pumps (4) produce the impulsion of the beverage contained in the tank (2) towards the beverage dispenser (9). In addition, said drive pumps (4) are configured to generate a pressure signal (SpBI (3a, 3b)) indicative of the pressure of the drive pump (4) of the beverage dispensing line (3a, 3b) a The one that is connected.

Likewise, the foam detectors (6) are configured to generate an electrical signal (Sde (3a, 3b)) indicative of the emptying of the tank (2) of a beverage dispensing line (3a, 3b).

For the management of this installation (10) it comprises a control circuit (1) formed by an input module (7) and a processing module (8) to receive and process

respectively the pressure signals (SpBI (3a, 3b)) of the discharge pump (4), (SpBG (3a, 3b)) of the gas contained in the gas bottle (16) and (Sde (3a, 3b)) of emptying the tank

(2) in order to:

 generate and send an off or on signal to the booster pump (4) in case the pressure signal (SpBI (3a, 3b)) is lower or higher, respectively, at a preset threshold for the operation of the drive pump (4),

 generate and send a shutdown signal to the discharge pump (4) after receiving a pressure signal (SpBG (3a, 3b)) indicative of the lack of gas pressure contained in the gas bottle (16), and

 generate and send a shutdown signal to the discharge pump (4) after receiving a signal (Sde (3a, 3b)) indicating the emptying of the tank (2).

As can be seen in figure 1, the inlet module (7) is in communication with the drive pump (4), the foam detector (6), and the pressure sensor (5) of each beverage dispensing line (3a, 3b), while the processing module (8) is in communication with the drive pump (4) of each beverage dispensing line (3a, 3b).

On the other hand, a control device (14), shown in Figure 2, comprises the aforementioned control circuit (1) and, in addition, an electrical differential (11) to protect the control circuit (1) from electrical shunts , a power supply (12) adapted to regulate the power supply of the different elements of the device (14) and a screen (13) to show information on the operating status and indicate the type of fault that may exist.

Turning now to the object itself of this Addendum, it should be noted that according to the embodiment shown in the figures, especially Figure 1, it can be seen that the control circuit (1) comprises an input module (7) and a processing module (8).

Thus, while the input module is responsible for receiving the electrical signal (Sc (3a,

3b)) sent by a flow meter (15) for each beverage dispensing line (3a, 3b), the processing module (8) is responsible for processing said signal, in order to generate an alarm signal for the user , as well as to stop the operation of the impulse pump (4), since this electrical signal (Sc (3a, 3b)) is indicative that a purge key of the foam detector (6) is open at a different time to the change of deposit (2).

On the other hand, the installation (10) of the present invention comprises, in addition to said defined control circuit (1), a flow meter (15) located at the outlet of the purge key (not shown) with which the power detector has foam (6), configured to generate an electrical signal (Sc (3a, 3b)) indicating that there is liquid passage through said purge key.

More specifically and as can be seen in said figure 1, each flow meter (15) of each foam detector (6) is connected to the input module (7) of the control circuit (1) of the installation (10) , such that said input module (7) receives an electrical signal (Sc (3a, 3b)) indicative of the measurement made by said flow meter (15). Likewise, the processing module (8) is in communication with the drive pump (4) of each beverage dispensing line (3a, 3b).

In this report, a control method of an installation such as that defined with a control circuit (1) as previously described is also presented, where said control method comprises a first stage in which the electrical signal is received (Sc (3a , 3b)) generated by the flow meter (15) located at the outlet of a purge key of the foam detector (6) of one of the beverage dispensing lines (3a, 3b) of the installation (10).

This electrical signal (Sc (3a, 3b)) sent by the flow meter (15) is subsequently processed by the processing module (8) of the control circuit (1), in order to determine or discriminate whether the measurement made is being occurring during the normal and usual process of change of deposit (2) or barrel, in which case no action is taken, or on the contrary, the measurement is taking place at a different time than the change of deposit (2) or barrel , which would indicate that the purge key of the foam detector

(6) it has remained open and, consequently, beer is being dumped down the drain, in

in which case the second stage of the control method takes place, consisting of generating a

warning or alarm signal to the user to proceed to its closure, at the same time as the

third stage of said control method, which consists in generating and sending a signal of

stopping the operation of the drive pump (4) connected to that line of

5

beverage dispensing (3a, 3b) from which the electrical signal (Sc (3a, 3b)) has been received from

flowmeter (15) associated with the foam detector (6)
