Brix Setup
If initial concentrate brix is 60 and required mixing ratio is 6+1/6:1 (6 ounces water to one part concentrate),
then brix of ready to drink mixture of a concentrate and water should be 10.
To measure brix level, a refractometer is used to show sucrose content in a drink by measuring change of the light
diffraction in the water caused by change of viscosity due to sucrose content.
The correct ratio is achieved by controlling water and a concentrate flow to the mixing device, in this case mixing
chamber. Brix on each dispensing head is preset in the factory. In the field, the brix needs to be fine-tuned to the
