To measure the density of dredging slurries without the use of radioactive sources, Rhosonics has developed the ultrasonic SDM density meter. Since 2009, our company has been continuously developing and improving non-nuclear density meters for inline measurements on various dredging vessels. Consequently, we have gained significant expertise in this field. The SDM device is exceptionally user-friendly, requiring no licensing, and provides dependable density values to monitor and enhance production output. Moreover, the instrument can be controlled, including calibration, either via an RCU Remote Control Unit or through HART communication. Ultimately, we firmly believe that our instrument is a safer and more cost-effective alternative to radiation-based density meters.
