Introducing the Rhosonics CDM – Chemical-based Slurry Density Meter to measure density in real-time. Rhosonics CDMs boast a robust design featuring sensors manufactured from highly corrosion and abrasion-resistant materials, ensuring resilience in the face of even the roughest process conditions.

The major features and benefits of the CDMs are:

  • Real-time density monitoring
  • Safe technology (non-nuclear)
  • Corrosion and abrasion-resistant sensors
  • Easy operation and installation


The CDMs can be installed in line with the use of a pipe integration system, which can be a Wafer or a spool piece. The best fit depends on the process data, and these systems are tailor-made to match the existing piping specifications (flange standard and pipe ID). The CDMs can also be mounted to tanks with the use of sensors designed for that purpose.


The Rhosonics CDM is a game-changer in various industries, catering to the measurement needs of chemical-based slurries and liquors. Industries benefiting from this technology include:

  • Mining
  • Ore Refineries
  • Pulp & Paper
