<p>A binary syrup metering system (10) for beverage dispensing including a pair of syrup containers (12,14) holding different syrup components, a meter device (16) with two inlets (22,24) connected one to each container (12,14) and a single syrup outlet (26) connected to a dispenser (20). The metering device (16) includes a flow channel (34,36) therethrough for each component, means for equalizing the pressure in each channel (42,44,46,52), and a metering orifice (68,70) downstream from the pressure equalizing means. This pressure equalization in combination with the metering orifices (68,70) provides the necessary flow control and a constant predetermined volumetric ratio of the two syrup components when mixed to form the complete syrup.</p> |
