Flow-Viz is an innovation which improves process and quality control in fluid industrial operations. It replaces time-consuming off-line measurements in the quality control laboratory with continuous real-time process monitoring taking place directly in the production line. Flow-Viz includes a sensor unit, operator’s panel and software to analyse viscosity and flow-profiles. Pilot tests have been conducted on products such as cement grout, yoghurt, soup, bio-chemicals like ethanol and paper pulp.
