An in-line sensor apparatus and method for the control of fluid manufacture, especially the manufacture of carbonated beverages, provides precise and reliable monitoring of several characteristics of the material of interest. The apparatus consists of a sensor head that is mounted at a point in the process where control is needed. A controlled wavelength light is directed toward the fluid being monitored. The light is sensed directly and after passing through the fluid. Sensor data is processed into reference and quality signals. Fluid quality is predicted by processing these signals. |
