A dispensing system for a beverage comprises in a tap system a bore for housing a duct. Along the bore, close to or on the duct, at least two electrodes are provided such that at least at some locations along the duct, the two electrodes are provided opposite to one another with the duct in between, thus constituting a capacitor. An oscillating signal is provided to one electrode and a signal is read out from the other electrode. As a beverage is drawn through the duct in a container, capacitance of the capacitor changes.

The flowing beverage may have different characteristics, but capacitance may also change as the beverage in the duct is in conducting contact with a container that may be in contact with an earth contact. The change of capacitance results in a change of the amplitude of a detection circuit connected to the second electrode.

A measurement device for measuring a flow distribution of a liquid spray stream which has been atomized by a nozzle may comprise: a sensing wire; at least one further sensing wire; an electric power supply; a measurement unit; and a second grid of parallel sensing wires. The sensing wires may be positioned within a spray volume of the liquid spray stream and arranged in parallel with respect to each other to form grids of parallel sensing wires. The electric power supply unit may supply an electric current to the sensing wires. The measurement unit may measure an ohmic resistance change of the sensing wires. The first axis defined by the parallel sensing wires of the first grid and a second axis defined by the parallel additional sensing wires of the second grid may enclose a slanted angle.

The change of capacitance results in a change of the amplitude of a detection circuit connected to the second electrode.

A system for measuring product quantity may include a first plurality of sensor assemblies and a second plurality of sensor assemblies, the second plurality of sensor assemblies being laterally opposed to and aligned with the first plurality of sensor assemblies, wherein opposed pairs of sensor assemblies are configured to detect a presence of a product disposed between the opposed pairs of sensor assemblies.

A measurement system for providing real-time tracking. The measurement system includes a system tracking measurement unit, a system tracking processing unit, and a user interface device for receiving data corresponding to one or more system conditions over an electronic communications channel, the user interface device including a display. The system tracking measurement unit calculates temporal flow data when the orientation of one or more objects corresponds to an event trigger value and transmits the data to the system tracking processing unit. The system tracking processing unit determines one or more tracking parameters based on the temporal flow data. In addition, the system tracking processing unit determines one or more system conditions based on the one or more tracking parameters. The system tracking processing unit transmits data corresponding to the system conditions for display on a user interface device.

A counter having an actuating element (20) and a counting element (30) with toothing (32), the actuating element axially movable along an axis (X) between a rest position and an actuation position, the counting element mounted to rotate on an axis perpendicular to the axis (X). The actuating element has a first flexible tab (21) engaging the toothing to rotate the counting element in a counting direction when the actuating element moves into its actuation position, and a second flexible tab (22) engaging the toothing to rotate the counting element in the counting direction when the actuation element returns to its rest position. The first and second flexible tabs are resiliently biased radially inward into contact with the first toothing. The counter has a stop element (19) which engages the second flexible tab limiting radially inward movement thereof when the actuating element moves into and out of its actuation position.

A signaling apparatus paces a free pour count and choreographs a movement to stop pouring. The apparatus emits a first signal after an approximately 200-ms time interval and a series of subsequent signals every approximately 400-ms thereafter. The first time interval approximates a first time, measured from a moment the sensor detects the start of the pour, needed to dispense a first unit of beverage through the pour spout, minus a second time needed to react to a signal and stop the pour. The 400-ms time interval approximates the time required to dispense each subsequent unit of beverage through the pour spout. In one embodiment, the signaling apparatus emits sequential pulses according to the pattern Y-Y-Y-Y-G-Y-Y-R, wherein Y is yellow, G is green, and R is red, wherein each pulse represents a quarter-ounce increment, the green pulse represents a standard pour, and the red pulse represents a full pour.
