Abstract: An apparatus is provided for improving quality and increasing syrup yield within a beverage blending system. The apparatus and the associated method are adaptable to existing proportioning and blending systems or the appropriate control and measurement equipment may be installed alone to provide a highly accurate control of the blend. This control is a function of the mass flow of at least one of the components input to the proportioner. From this mass flow determination an adjusted volumetric flow value for the component(s) is determined. The ratio of the volumetric flow of the water to the syrup is used to determine a signal to control the proportional blending. Adjustment of the blend ratio is made by comparing the calculated ratio to the set beverage values. Control of the carbonation of the system is also incorporated as well as a device to fully saturate the CO.sub.2 into the liquid flow.
