7 Troubleshooting the ViscoSite Viscometer
7.1 Introduction to Troubleshooting
While the ViscoSite is designed to provide long term trouble-free operation,
troubleshooting is occasionally necessary when system behavior in the process
material is not as expected. This section will highlight commonly observed issues
that may arise with the ViscoSite and/or the process and discuss possible
solutions.
7.2 Changes in ViscoSite Behavior – Process Related?
Changes/fluctuations in temperature, density, flow rate, material structure
(settling, crosslinking, etc.) and pressure are just some of the variables that may
result in a change in the ViscoSite viscosity reading or behavior under process
conditions.
Experience has shown that unexpected instrument readings are often
attributable to
•
Short or long-term changes in the process
•
Batch to batch variations in raw materials used to make the material being
monitored in process by the ViscoSite Viscometer
•
Procedural changes in material production made upstream of the ViscoSite
Viscometer that affect the nature of the material measured by the Viscometer
and therefore the reading.
Review all upstream changes (reagent and process) for possible impact.
Trending of other process measurements during the period of unexpected
ViscoSite measurements may aid in the detection of any correlation, should it
exist, between other process parameters and the ViscoSite measurements.
