A switch, mounted on a standard beverage tap, provides an electrical signal indicating when beverage is being dispensed into a serving container. The electrical signal is applied to a monitor which measures the period of time that the beverage flows from the tap. As beverage dispensing occurs, a series of steps are taken which determine from the time measurements whether the dispensing is proceeding into one container, is complete, is part of a continuous pour into several containers or has been completed with a subsequent single container pouring operation occurring. That determination is based on whether the period of time is within a range indicative of dispensing the beverage into a single serving container. When that determination is made a serving container count is incremented. The monitor also uses the measured time period to detect when the tap is opened for longer than the typical time required to fill a single beverage container. In response to that detection, a numerical estimate is made of how many serving containers were filled while the beverage tap was open and the numerical estimate is added to the serving container count. The measured time that the tap was open also is employed to calculate the quantity of beverage that has been dispensed.

A dispenser is programmed to automatically dispense a beverage into a plurality of different size containers by storing therein a volume designation for each size container. The flow rate of beverage through the dispenser is determined. To do so, a user manually operates the dispenser to fill a given container with the beverage while the dispenser measures the filling time. The dispenser calculates a beverage flow rate from the volume designation for the given container and the filling time. Then the flow rate and volume designations are used thereafter by the dispenser to derive a dispensing time for each different size container. Thus the dispenser is able to derive dispensing times for each container size from filling only one of the containers. A unique dispenser valve also is disclosed.

A user interface including a dual navigational menu system forming part of a configuration or programming procedure in a process control device such as a flow controller. The controller includes key pad by which the user enters instructions and data into the device, a display for displaying alphanumeric information and a key pad monitoring means for detecting a predetermined user input indicating that a configuration mode is desired. When in the configuration mode, the pressing of direction keys is detected to sequentially advance through a menu system comprised of a matrix of menu items arranged in rows and columns. Means is also provided for detecting the entry of position data which operates to directly select a given menu item to obviate the need for sequentially advancing through all prior items in order to reach the desired menu item. When a given menu item is activated, random access memory forming part of the device is used to store data entered by the user. A help system is also implemented including a key designated as a 'help key' which displays context sensitive information for an activated menu item whenever the 'help' key is pressed.
