The present invention relates to a method and apparatus for improving quality and increasing syrup yield within a typical beverage proportioning system (50). The invention controls the proportional blending as a function of the mass flow of the components input to the proportioner (50). The mass flow determination is made by Coriolis-type mass flow meters (54, 60) positioned within the feed lines (52, 58) for the water and syrup respec-, tively. From this mass flow determination an adjusted volumetric flow value for each component is determined by a master controller (68). The ratio of the calculated volumetric flow of the water to the syrup is used to determine a signal to control the …

Why it's free to use
- Filed February 19, 1991 and granted January 1, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 19, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
