Non-Nuclear Slurry Density Measurement

The Slurry Density Meter (SDM) from Rhosonics enables end users to implement density measurement in their process without introducing a hazardous material to site, ensuring safety and sustainability.

The density measurement of slurries in mineral processing and dredging applications has relied heavily on nuclear technology for the past 50 years. Until now, there have been no reliable alternatives to nuclear density gauges. Rhosonics was founded in 1992 in The Netherlands, and over the years have developed sustainable and safe measuring instruments to replace radiation based density measurement devices.

The Slurry Density Meter (SDM) from Rhosonics enables end users to implement density measurement in their process without introducing a hazardous material to site, ensuring safety and sustainability. Wherever nuclear gauges are currently in use, they require documentation and licensing for:

  1. Installation
  2. Storage
  3. Inspections
  4. Transportation
  5. Disposal

These hurdles carry costs initially and over the life of the instrument, they do not apply to the SDM due to the use of acoustic impedance to determine slurry density.

Once the SDM has been installed on site the span may need to be adjusted once a slurry sample has been taken. The simple calibration can be carried out by an instrument technician or other qualified personnel.

Slurries up to 3.000 SG with flow velocity lower than 5m/s are ideal for accurate and reliable readings. Currently there are over 800 SDM’s successfully implemented in various slurry applications around the world.
