9670: Slurry Analyser
The Rhosonics non-nuclear Model 9670 Slurry Analyser offers information about the dissolved solids (TDS), suspended solids (TSS) and density in your chemical liquid or slurry and is designed for a wide range of industries and applications. The model 9670 has a robust design with sensors that are made of highly corrosion and abrasion resistant materials to withstand rough process conditions. The analyser is mostly used for measurement of the solid content in chemical slurries. However, the instrument can also be used to measure multiple other parameters of a liquid or slurry such as the density in g/l, concentration (TDS) in wt% and the temperature.
Features and benefits
Major features and benefits of the Model 9670:
- Real-time in-line solids and density monitor
- Wide range of measuring parameters
- Non-nuclear technology
- Corrosion and abrasion resistant sensors
- Easy installation and maintenance free
- Outputs for process control and alarm signal
Technology
Model 9670 can measure the following parameters:
- Attenuation (solids)
Particles are absorbing ultrasonic energy. Model 9670 measures the loss of energy over a particular distance. Those losses are a value for the amount of solids, expressed in weight percent (wt%) or gram per liter (g/l).
- Acoustic impedance (density)
The acoustic impedance is the reflection of energy at the interface between the sensor and slurry or liquid.
- Sound velocity (concentration)
The sound velocity is determined by measuring the time that the ultrasonic signal is traveling over a known distance. This distance is from the sending to the receiving sensor and is equal to the pipe diameter.
- Pt100 sensor (temperature)
The temperature is measured by a Pt100 probe to compensate for temperature influences.
Installation
There are multiple configurations available for the solids meter, the final choice depends on the specific applications of the customer.
The model 9670 can easily be installed in pipe lines by 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.
For tank installation, Rhosonics will use another sensor type. This configuration offers a specially designed fixed UTP tank probe and uses reflection technology with one ultrasonic probe instead of two compared to the model 9670. This product is available as the model 9680 slurry analyser.
