A flow meter for use in monitoring unit and total quantities of a dispensed fluid, such as draft beer, includes a motion detection switch inside a housing and is coupled to a valve which controls the fluid flow. The switch provides an electrical indication during periods when the valve is open. A totalizer including microprocessor circuitry totalizes the amount of fluid passing through the valve based upon an adjustable, predetermined flow rate setting. An indicator is also coupled to the totalizing circuitry to provide an indication when a unit quantity has passed through the valve at the predetermined flow rate. The totalizer further totalizes the number of occurrences of the unit quantity or any other preselected quantity.

An apparatus for measuring and totalizing an amount of a fluid dispensed through an outlet from a reservoir of said fluid, said outlet of the type controlling the flow of said fluid from said reservoir by movement between open and closed positions, said apparatus comprising: position detecting means coupled at said outlet for detecting said movement between said open and closed positions and providing an electrical output responsive thereto: totalizing means receiving said output from said position detecting means and totalizing an amount of said fluid passing through said outlet based on a setting in said totalizing means for a predetermined flow rate; means for changing said totalizing means to a setting representative of another predetermined flow rate; a count display; means for coupling said count display to an output of said totalizing means whereby a count representative of said amount of said fluid may be displayed; a key operated switch; circuit means coupling said key switch to said totalizing means; means coupled through said key switch to said totalizing means for providing a signal to said totalizing means responsive to operation of said key switch to clear said amount therefrom; indicating means coupled to a first output of said totalizing means; and means for energizing said indicating means for each occurrence of a preselected amount of said fluid passing through said outlet at said predetermined flow rate.
