L-Vis 510 and L-Vis 520 Ex
More than an instrument. A solution.
Bringing lab measurement inline
- Higher product throughput: The number of lab measurements can be reduced from once per hour to once per day.
- Increased output product quality: Ceramic’s waste, for example, can be reduced by 20 % as continuous inline measurement helps avoid laboratory-related sample preparation issues such as the influence of ambient conditions or read-off errors.
- Reliable inline performance: Being the leading supplier for lab rheology instruments, Anton Paar’s expertise ensures an excellent correlation between inline sensors and lab instruments under a wide variety of operating conditions.
- Adjustable shear rates allow for further improving the lab-to-process correlation by adapting shear rates in such a way that they are closer to those of lab instruments.
Best-in-class analysis of shear-dependent samples
- Get more meaningful and detailed information on your sample’s properties by applying low shear rates down to 10 s-1. Measure, for example, shear-thinning polymer solutions in their low-shear plateau rather than in the shear-bending area.
- Accurately track varying flow behavior throughout different process steps by choosing between three different rotation speeds.
- The influence of temperature variations is minimized due to temperature-compensated viscosity values.
Rely on results, even under harsh process conditions
- The instrument can be installed directly in the product flow.
- Pressure drops and changes of flow velocity up to 2 m/s do not influence the measurement.
- External forces, such as bearing and sealing frictions, do not influence the measurement result.
- Measurements of inhomogeneous fluids and suspensions can be performed, maintaining excellent repeatability.
Various process installation and communication possibilities
- L-Vis can be installed in a stirred tank, in the main line, and in a bypass line. The innovative measuring principle always forces a proper sample exchange.
- Multiple spool pieces and process connections make the installation as easy as possible.
- All relevant fieldbuses as well as an analog 4-20 mA signal are available to ensure communication to your PLC/DCS.
