Inline Viscosity Measurements

Inline viscosity measurements can give continuous, realtime readings of a fluid’s viscosity during processing and consequently, can provide a means to automate the viscosity control of process fluids. While it is difficult to control all factors in the process that can affect a fluid’s viscosity, if these factors are kept relatively constant, then good control can be achieved.... More
