Résumé : |
Quick and accurate viscosity measurement is very often critical for a fast and efficient quality control process in a paint manufacturing plant. We describe the testing of an automatic process viscometer that for the first time makes it possible to measure the viscosity profile in the process and to use the data for process control. |
