Inline integration of process viscometers

Various output signals allow you to integrate the device into existing process control systems.

MARIMEX viscosity sensors can be easily integrated into your new and existing systems. Even if your production is restructured for process-related reasons, the viscometer can continue to be used.

With our accessories you can measure the dynamic viscosity directly in the process in almost any application (inline viscosity measurement).

With our viscosity sensor you increase your process quality and avoid faulty batches

Measuring viscosity is an excellent way to achieve higher quality in the process.

Inconsistent product quality and defective batches can often be traced back to unnoticed changes in process conditions.  MARIMEX® viscometers help you maximize your yield and avoid production-related revenue losses..  With our viscosity measuring device, the ViscoScope® from MARIMEX®, you can measure viscosity in real time directly in your process. Use the newly acquired knowledge to optimize and control your manufacturing process

Inline viscosity measurement maximizes your yield & saves costs

Through precise and reliable process knowledge of the viscosity parameter, you can achieve higher quality in your process.

Our inline viscosity measuring device supports you as a user in achieving optimal process control. With our process viscometer, you use only as much raw material and energy in your process as you actually need to achieve the desired end product. You can use the measurement results, for example, to control dosing quantities and mixing ratios or to regulate the temperature of your manufactured product.

Rely on the quality parameter viscosity & trust ViscoScope® from MARIMEX®.

Work with our application engineers to find out how you can use viscosity measurement in your specific application to improve process quality. We have already successfully installed our measurement system for a large international customer base.

Inline Viscosity Meter: Frequently Asked Questions

ViscoScope® from MARIMEX®

In all liquids, from low-viscosity emulsions to high-viscosity polymer melts, the measurement remains reproducible, regardless of whether the media are non-Newtonian or Newtonian.
The viscosity sensor can be manufactured with any standard or customized flange. Common flange sizes range from DN50/2" to DN250/10". We can also offer custom designs with customized dimensions, as well as antiseptic fittings for absolutely dead-space-free installation. Ask us about your "custom flange" – so far, we have been able to realize every process connection!
ViscoScope viscosity sensors are based on the principle of oscillating torsion. This measuring principle makes the inline process viscometer independent of flow direction and flow type. It doesn't matter whether the flow is turbulent or laminar, or whether the sensor is subjected to sideways or axial flow. This has been proven by tests with shear-rate-independent oils. Furthermore, the viscometer is insensitive to gas bubbles in the medium. Oscillating torsion generates a shear wave that penetrates the medium only very slightly. This means that if a gas bubble touches the sensor, only the liquid film of the glass bubble is measured. The shear wave does not penetrate the gas bubble.
Factory multi-point calibration with certified, Newtonian calibration oils enables reproducible results, regardless of whether the fluid being measured behaves Newtonian or non-Newtonian. Almost all fluids are non-Newtonian and therefore shear rate-dependent, meaning their viscosity changes with mechanical stress. Significantly higher shear rates occur in production processes than in laboratory measurements. To compare process viscosity with laboratory viscosity, a correlation must be determined empirically. And don't forget: Calibration enables measurement repeatability, e.g., after a sensor has been repaired, when using multiple systems in the same application, or after conversion to a different system. In other words: 5,000 mPa.s remains 5,000 mPa.s.
The transmitter excites the sensor's probe at its resonant frequency with a very small amplitude, causing it to twist. When the probe is immersed in a liquid, it "rubs" against the adjacent liquid layer and experiences damping due to the viscosity. This is where it differs from comparable systems: With fast PID control, the transmitter compensates for the amplitude loss caused by the damping, i.e., the amplitude is kept constant despite changing viscosity. This changes the drive voltage, which is the basis of the viscosity value. Using this technology, the ViscoScope® viscometer measures dynamic viscosity x density in mPa s x g/cm³ (η x ρ), responds to viscosity changes in less than 2 seconds, and enables the detection of even the smallest differences, even under harsh process conditions. By driving the probe at its resonant frequency with the low amplitude, the probe is not subject to material fatigue. You won't find any moving parts, joints, or seals in our sensor, as all process-wetted parts are welded. The result: a maintenance-free, extremely durable, and reliable process viscometer.
No, you can install the sensor in any orientation in a reactor, vessel, or pipeline. However, the installation should make sense so that the measurement results in optimal process control and regulation. Don't hesitate to contact us; we'll be happy to help with our diverse experience.

Due to the low amplitude at the system's resonant frequency, the sensor is not subject to material fatigue or deterioration. Since the probe is completely welded, there are no moving parts, bearings, or seals on the sensor. We have numerous applications where the systems have been running 24/7 for more than 10 years. A calibration check of the viscometer is not required. However, quality management regulations often require an annual calibration check. Please contact us if you would like a system check.
