Vision can also effectively handle applications involving the monitoring and control or produced water concentration, water- in -oil analysis, multi- cut sand, oil and water analysis, and even flame and tube analysis in the refining process with the benefit of the operator's visual optimization. Vision analysis, as proven in many applications such as polystyrene bead manufacturing, sugar crystal growth, cell growth, and abrasive manufacturing to name a few, provides an extra dimension to process analytics that enables the process engineer to make evaluations based on his own expertise and to use this information to better set software parameters that enable the system to more accurately analyze and control the process.
