SDM SERIES - SLURRY DENSITY METER PRODUCT INFORMATION CONTINUOUS IN-LINE MONITORING & PROCESS CONTROL
SDM Non-nuclear Density Meter INTRODUCTION RHOSONICS is proud to present a new generation non-nuclear density meters based on ultrasonic technology. After years of being successful as the only alternative for nuclear technology in density measurement of abrasive slurries we introduce the Rhosonics SDM Slurry Density Meter. This new density meter makes use of the same ultrasonic technology but with new materials, better electronics and innovated calculations. SLURRY DENSITY METER The Rhosonics Slurry Density Meter has its sensor, analyzer, cable and software integrated in just one system. Therefore, the new density meter weighs less than its predecessor. In addition, the HART protocol is integrated to improve communication. The SDM has new sensor material and is therefore suitable for new and more challenging applications. These improvements result in higher accuracy and better stability of the new density measurement device. INDUSTRIES SDM is used in the following industries: Mining and Minerals Dredging Building Materials Energy & Power supply Any other industry or application where density measurement is required. The Rhosonics Slurry Density Meter with wafer installation IMPROVEMENTS The Rhosonics SDM has a single probe, employing a unique measuring technology. This enables very accurate density measurements in light to very dense slurries. The SDM uses new sensor technologies: The PEEK material is replaced by a ceramic material. This gives the probe better ultrasonic properties like a stronger and more intense signal. The sensor tip is extended which results in a longer life cycle of the new sensor. The sensor and housing can be easily separated which makes the SDM very flexible in case of maintenance.
BENEFITS Non-Nuclear technology Environmental friendly Less operation costs Safe and durable probe system FEATURES High accuracy and reproducibility Suitable for all types of slurries Compact integrated system Easy to operate by simple user interface Process connection via HART and 4-20mA Continuous data & system logging Sensor & Electronics are easy to separate SDM is insensitive to wear because of new AWD (Auto Wear Detection) technology. Stronger and more intensive signal because of new ceramic materials HOW TO INSTALL The following guidelines apply to all probe types: Install the probe with 5xD length of straight pipe length upstream or 3xD of straight pipe length downstream. Vertical pipe installation is preferred. Horizontal pipe installation: Sensors must be installed sidewise. HOW IT WORKS The density measurement is based on measuring the acoustic impedance of the slurry. The attenuation of the ultrasonic signal is measured, which is translated into density. INSTALLATION METHODS Ultrasonic measurement principle Rhosonics offers different installation methods to fit every customer s need. The major installation methods are discussed below. UFTC Spool An UFTC (Ultrasonic Flow Through Spool) is a metal pipe piece which can be mounted between two flanges. The spool type and size are on customers request. Weldolet Rhosonics designed a special low cost Weldolet solution for very abrasive applications, such as dredging. The Weldolet can be installed by drilling a hole of 36 mm in a steel pipe. On the outside of the pipe, the Weldolet is welded-on so the sensor can be fitted in. UWC Wafer The UWC (Ultrasonic Wafer Cell) is a synthetic 60 mm thick ring made of UHPE (Ultra High Density Poly Ethylene). It can be clamped between two flanges in almost every pipe system. Rhosonics always tries to guarantee the maximum performance and therefore produces custom-made wafers. The thickness of a liner (if present) and the internal diameter of the pipe are important dimensions to guarantee flush mounted installation.
The best alternative to nuclear density meters. A TYPICAL APPLICATION SDM density meter can be used in many applications to measure the density of a slurry. For the mining industry, typical applications are a thickener underflow and a cyclone feedline. Also applications like dredging, power plant ash, lime stone milk and many others are possible. The measured density value is used for process control but also in combination with flow measurement for production yield. The Rhosonics ultrasonic density meter is in general THE alternative for nuclear density technology for heavy slurries with a high abrasive impact.
