A dynamic microwave sensor system able to monitor compositional changes of the basic liquids used in the polyurethane industry (polyol and isocyanate) was designed, installed in the production line and tested. These liquids are continuosly flowing into hermetic pipes and its desirable properties are gradually degraded in time. The sensor provides on- line information about the state of the liquids by means of microwave non-invasive measurements. This information can be used in real-time non-destructive quality control processes. The sensor technology described here can be used for the monitoring of other liquids used in chemical industry.
