ABSTRACT:
There is disclosed a fluid flow metering device for use, for example, in a system for preparing a carbonated beverage wherein deaerated water and a beverage concentrate are mixed together in closely controlled proportions. The system can also include a vessel for storing a quantity of water and a deaerator for removing air from the water. The fluid flow metering device controls the rate of water flow from the vessel to the deaerator and is responsive to the water flow rate demand of the deaerator. The metering device includes a valve block having a fluid conducting channel for conducting water from the vessel to the deaerator, and a bore intersecting the channel. A valve element is disposed within the bore and is movable into and out of the channel for modulating the water flow rate through the channel. Flow rate demand sensing means within the deaerator provides a control signal responsive to the water flow rate demand of the deaerator control means are coupled to the valve element and to the sensing means for moving the valve element in response to the control signal so as to modulate the water flow rate through the channel in direct relation to the flow rate demand of the deaerator.
