Rheology

Rheology is the science of flow and deformation. It is normal to consider simple fluids as having a viscosity value (say 1000 poise) and a complex fluid as having a rheological model (say Carreau model with known values for the parameters).

Manufacturing plants can implement the measurement of rheology in a number of ways with varying levels of accuracy, precision, stability, timeliness, reliability, wastefulness etc. The use of "In process measurements" is the modern solution to making rheology measurements on a process plant - the process is the rheometer. This gives the highest level of automation, with the lowest cost, the highest reliability and no waste. You can't get better !

DrRheology we can implement in process measurement of both simple fluids and complex fluids in your process. These measurements can be used to control the process, or to qualify the manufactured material as a QA/QC tool. Measurements and analysis can be integrated into the local control system or implemented on a stand alone computer with logging and communications.
