    • A beverage dispenser (100) for dispensing a carbonated beverage from a beverage source (125) into a receptacle (150) includes a housing defining an interior volume and having a first surface proximal to the beverage source and a second surface distal to the beverage source. The beverage dispenser further includes a conduit in fluid communication with the beverage source entering the first surface of the housing and terminating proximate the second surface of the housing. The dispenser also includes a multi-nodal flow rate controller disposed within the interior volume of said housing in contact with said conduit and a subsurface dispensing nozzle in fluid communication with the terminal end of the conduit. The flow through the conduit to the subsurface dispensing nozzle is compensated to maintain substantially hydraulic beverage flow within the conduit by adjusting the contact between the multi-nodal flow rate controller and the conduit.
