    Automatic Brix control is customised to suit the plant configuration on which it is installed, but typically one of two methods is used:
 
 a) Dosing pump control
 
 b) Valve orifice control
 
In the first case the controller drives a motor that adjusts the head position of the dosing pump. In the second it controls the water or syrup flowrate by adjusting the micrometer valve. The Brix controller can receive its operational parameters from the IB-05 Analyser System or remotely from MultiLab-III in the laboratory.

 Automatic CO2 control also uses one of two methods:
 
 a) CO2 injection flow control
 
 b) CO2 saturation tank pressure control
 
 In the first case the controller modulates a flow valve to maintain a constant desired flowrate to the CO2 injection feed piping. In the second the controller monitors saturation tank pressure and modulates a pressure regulator to maintain a constant desired pressure in the tank.
