Abstract: An apparatus for determining Brix utilizing a liquid sugar or syrup and a water or water based liquid stream. The apparatus includes a conduit for the water, a conduit for the sugar syrup, and a third conduit connected to the first and second conduits for use as a mixture stream of the syrup and the water. Pressure is applied to the sugar syrup in the first conduit and the water in the second conduit. The pressure of the water in the second conduit is predetermined to equal or lie at a greater value than the pressure applied to the sugar in the first conduit. A regulating mechanism is found in the third conduit for setting a value of the Brix of the mixture stream, detecting the actual Brix concentration, and a valve adjustment to the water stream responsive to a differential between the actual and set values of Brix in the mixture stream.
