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

Rhosonics CDM stands for Chemical-based slurry Density Meter and that category of instruments allows measuring density in real-time. The CDMs have a robust design with sensors that are made of high corrosion and abrasion-resistant materials to withstand rough process conditions.

A Chemical Density Meter can be used in a variety of applications whenever there is a need for measuring chemical-based slurries or liquors. Some of the industries where this technology is used are:

• Mining
• Ore refineries
• Pulp & Paper

CDM 9670

For in-line measurement of TSS (Total Suspended Solids) or TDS (Total Dissolved Solids), we recommend the use of our Chemical Density Meter 9670. Also, the CDM 9670 is ideal for monitoring slurries in a small pipeline. Model 9670 uses two hybrid PEEK sensors, facing opposite directions. In addition, these ultrasonic sensors measure a wide range of physical parameters, including density and the velocity of sound to determine the amount of either dissolved or suspended solids. Thanks to the powerful sensors virtually all slurries up to 2500 g/l is measurable. This product is mainly used for measuring drilling mud and cement slurries.

CDM 9680

Chemical Density Meter 9680 offers real-time information about multiple parameters of liquids or slurries. Only one sensor can measure the dissolved solids (TDS), suspended solids (TSS), and density at the same time by reflection technology. Additionally, the sensor can withstand rough conditions of chemicals and mineral slurries thanks to the corrosion and abrasion-resistant sensor materials.

In the process, CDM 9680 can be installed in a tank or in a pipe with a small diameter. For bigger pipe diameters the requirement is to use a different analyzer, CDM 9670. Besides, this analyzer has two sensors for transmissive measurement offering the same measurement parameters.

There are multiple configurations available for the solids meter, the final choice depends on the specific applications of the customer.

Chemical Density Meter 9670

The Chemical Density Meter 9670 is easily installed in pipelines, this is through mounting the sensors onto a metal UFTC spool piece or with a flow-through wafer. With both installation methods, there will be zero intrusion of the ultrasonic sensors in the process liquid or slurry.

Chemical Density Meter 9680

Tank installation is through a UTP tank sensor or UHP insertion probe. The UTP probe can be mounted on top of a tank or in an open channel. For side-mounted installation, a UHP probe will be used.

Pipe installation is through a metal pipe piece (UFTC spool) or with a PEEK wafer (UFTW). Both methods use one sensor that measures the sound velocity after reflection at the pipe wall. For pipes with a bigger diameter, CDM 9670 is preferred.
