Ultrasonic

Rhosonics introduces the newest generation non-nuclear density meter, the SDM Slurry Density Meter. This instrument is suitable for real-time density measurement in all kinds of slurries. The product uses sustainable ultrasonic technology and is specifically designed for dredging and mineral processing applications after ten years of experience with the predecessor, the model 9690 density meter. The SDM uses a non-intrusive ultrasonic sensor to measure the real-time density of mineral slurries under high density levels and at very large pipes.

Technology

By measuring the acoustic impedance of a slurry, the SDM calculates the density of the slurry real-time during the process. The sensor is made of stainless steel and ceramic material. Because of the new sensor material, the sensor has lots of better properties. By making use of ceramics material, the ultrasonic signal is more brightful and powerful than before. Also, the sensor is more wear resistant than its predecessor, model 9690. Installation is easy and can be done by means of wafer cells, spool pieces or a weld-on piece (weldolet). The weldolet technology is a low-cost solution, especially for larger pipe sizes, since this method only requires a small hole in the existing pipe.
