With the advent of smart or intelligent field devices, a wealth of digital information has become available. However, what does the host system do with these data? The field device transmits a bucket of bits to the host system. How are these data converted into information that a human can interpret? Where is the information displayed? Should the information be stored as persistent data? These questions...

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 (such as temperature, air bubbles, shear history, turbulence and so on), if these factors are kept...
