Measuring viscosity in anaerobic (co) fermentation processes

In anaerobic (co) fermentation processes, there is a good chance that particles / contamination are present in the process fluid, such as biomass that - depending on the species - can also contain sand or soil. Fermentation also releases gas and (gas) bubbles will form. A stable viscosity measurement that is not damaged by exceeding the pressure of the viscosity, sanding of particles or adhesion of chemical substances is a must have. Also, the viscometer sensor performance should not be disturbed by particles or bubbles. Finally, turbulences can cause instability in the product to be measured, which can be overcome with a stable viscometer (for example with an integrated flow damping system). There for it's important to challenge your supplier with these five questions for the right viscosity solution for your application.
