Inline Industrial Viscometer

Short Description:

The inline industrial viscometer enables real-time continuous viscosity measurement in industries like petrochemical (crude oil, heavy oil, lubricants), food and beverage (syrup, milk, jam), coating and ink and pharmaceutical (tablets, capsule). Direct fluid viscosity measurement in production lines eliminates offline sampling and manual testing for long-lasting reliable performance and high accuracy. Seamless integration into production control systems allows immediate tweaks to temperature, pressure or additive dosage and avoiding off-spec products.

Working Principle

The viscometer industrial online or industrial inline viscometer features a rod-shaped sensing element, which vibrates at a fixed frequency and twists torsionally along its central axis. As the element shears through the fluid over its surface, it loses energy due to viscous drag forces. These forces change based on the fluid’s viscosity: the higher the viscosity, the greater the drag, and the more energy the element dissipates. This energy loss is detected by the viscometer’s electronic components. The transmitter then processes this signal to output a clear, readable viscosity value, delivering direct insights into fluid conditions during production.
