Abstract
A binary syrup system for beverage dispensing including a pair of syrup containers holding different syrup components, a metering device with two inlets connected one to each container and a single syrup outlet connected to a dispenser. The metering device includes a flow channel therethrough for each component, a diaphragm device for equalizing the pressure in each channel, and a metering orifice downstream from the diaphragm device. This pressure equalization in combination with the metering orifices provides the necessary flow control and a constant predetermined volumetric ratio of the two syrup components when mixed to form the complete syrup.
