WORKING PRINCIPLE

CleanWaveTM technology is integrated with Rheonics inline viscometer or Rheonics inline density meter and viscometer to create SlurrySense, a measurement probe that prevents deposits from forming using an inbuilt vibrator. The CleanWaveTM vibrations can be used continuously or intermittently to, respectively, prevent or slough off deposits. With the sensor probe cleanness maintained, the Rheonics inline viscometer or Rheonics inline density meter and viscometer can continuously provide reliable consistency readings without the need for operator cleaning interventions.

INSTALLATION
Robust and Compact Process Density + Viscosity meter

Custom Length

Rheonics SlurrySense is easily extendable to customize the length required to immerse the probe in the slurry, adapting to different slurry drum dimensions

Mounting accessories

Rheonics offers mounting accessories to ensure a correct mount at a fixed point while not interrupting system operation

Ease of installation

Possible with standard accessories directly available from Rheonics and global partners, onsite personnel available if needed
