Nanjing Pulaisen Instrument Co., Ltd. collaborates with numerous companies serving the mining industry, committed to continuously introducing advanced foreign technologies and equipment to meet domestic demand for online instrumentation in the mining sector.
The sludge‑interface meter from Nanjing Pulaisen Instrument Co., Ltd. is widely used in the non‑ferrous metals industry—covering alumina, gold, iron, copper, nickel, zinc, and other mineral sectors—primarily for sedimentation processes in mineral processing and for tailings thickening. This instrument breaks away from the traditional approach of relying on empirical control of settling tanks and thickeners; instead, it leverages ultrasonic principles to provide real‑time, precise monitoring of the depth of the sludge layer, the sludge interface, and the liquid level within the tank. It also measures the concentration of the overflow effluent. By furnishing customers with timely, accurate data, it enables dynamic monitoring of the settling tank, facilitates adjustment of underflow pump speeds, and optimizes flocculant dosing, thereby significantly enhancing control over the sedimentation process and helping to prevent serious operational incidents such as turbid underflow.
Nanjing Pulaisen Instrument Co., Ltd.’s sonar flow meters overcome the limitations of conventional measurement technologies such as electromagnetic, differential-pressure, and ultrasonic flow meters. By leveraging advanced sonar‑based measurement principles and adopting a novel installation method—eliminating the need for pipe‑penetrating fittings—the transducers are mounted directly on the exterior of the pipe wall. This approach not only prevents costly production downtime associated with instrument installation but also minimizes subsequent maintenance challenges. Furthermore, designed to withstand the demanding operating conditions of the mining industry, these sonar flow meters feature a robust, highly durable housing, laying a solid foundation for long‑term, reliable performance in harsh field environments.
Nanjing Pulaisen Instrument Co., Ltd.’s ultrasonic density meter is also designed to replace traditional nuclear‑radiation‑based measurement technologies. By leveraging the attenuation of ultrasonic waves, it measures the density of process slurries without handling radioactive materials, eliminating the need for complex approval procedures, posing no environmental risks, and requiring no special installation requirements—while delivering precise measurements with zero drift.
