Where metal is extracted from the soil, slurries are formed, in which particles are suspended. Other measuring principles generally measure the entire density, or the total solids concentration at best. Because of the ability of the Rhosonics Model 9620 analyzer to distinguish the total suspended solids (TSS) from dissolved solids (TDS), the Rhosonics Model 9620 is the ideal inline analyzer for virtually all slurries in the mining industry.
For this specific application, an integral sensor design was originally developed, consisting of a wafer to be mounted between flanges. This MCS-FTS integral wafer cell design utilizes ultrasonic technology to determine the solids content of the slurry passing through the wafer. Just as with the UFTC series sensors, the Rhosonics 9620 utilizes an advanced technique that precisely determines the acoustic properties of the acoustic pulses through the fluid, thereby allowing an inline measurement of the total suspended solids concentration.

The Flow-Through wafer sensor has no “elements” sticking into the pipe. It is completely smooth, allowing the slurry to pass freely and undisturbed, at the same time reducing the abrasion due to its construction of abrasive resistant plastic.

In conjunction with the Model 9620 in ½-19” rack-mount version, the system provides a reliable inline concentration signal, and enables the process operator to control the transportation of suspended material.
