Ternary Liquid Analysers

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

Features and benefits

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

Measuring methods

Acoustic impedance The acoustic impedance is the reflection ofultrasonic energy at the interface between thesensor and slurry or liquid.

Attenuation The attenuation is the loss of energy causedby solids in suspension in the liquid when theultrasonic wave travels from the sender to thereceiver.

Speed of sound The speed of sound is determined by measuringthe time that the ultrasonic wave takes to travelover a known distance in the liquid, known as thetime of flight.

Temperature The temperature is measured by a Pt100, used to obtain an accurate speed of sound.
