Viscoline - Inline Process Rheometer
. This molecular rearrangement can take some time to occur. In some instances, the rearrangement time can be very short, compared to the observation time, but in other cases it can take much longer. In those cases, what happens to a fluid before the moment of measurement can have a considerable impact on the actual measurement. Processes with non-Newtonian fluids passing through a pump, a filter, instruments with a smaller diameter than the pipe size, or those flowing through a sampling valve may... (read more)
