Flue-gas desulfurization in power plants

Online Measurement of Gypsum Slurry Density in Absorption Towers

In the wet flue-gas desulfurization process, real-time monitoring of gypsum slurry concentration is crucial for ensuring the quality of the by-product gypsum and the proper operation of equipment. However, conventional concentration meters—such as mass flow meters, tuning fork sensors, and differential pressure concentration meters—suffer from issues like radiation safety concerns, bubble interference, and scaling. Pisonics’ PS7000 employs ultrasonic technology for non-contact measurement, can penetrate bubble layers to deliver stable and reliable concentration data, and requires no maintenance, with a service life exceeding five years.

Flue-gas Desulfurization Wastewater Treatment in Power Plants

Online Measurement of Desulfurization Wastewater Density

In the flue-gas desulfurization process at power plants, online monitoring of the slurry density in the underflow from the thickener is critical. Conventional contact-type instruments are prone to scaling and corrosion, making it difficult to meet the demands of long-term, stable operation. Pisonics’ PS7000 acoustic impedance concentration meter employs a non-contact ceramic probe and a corrosion-resistant lining, effectively addressing severe corrosion and fouling while ensuring the accuracy and stability of the measurement data.

Nonferrous mine slurry

Online Measurement of Slurry Density in Non-ferrous Metallurgical Beneficiation Plants

In nonferrous metal concentrators, fluctuations in slurry density directly affect metal recovery rates and energy consumption. The PS7000 concentration meter employs ultrasonic non-contact measurement technology and features a flanged direct‑insertion installation, eliminating the wear and fouling issues common to conventional instruments, ensuring long‑term stable operation, and operating entirely without radiation, thus obviating the need to obtain a Radiation Safety License.

Coal heavy-media separation

Density Control of Heavy-Medium Suspensions in Coal Washing

In the heavy‑medium coal‑washing process, even slight variations in slurry density can significantly affect the ash content of the clean coal product. Conventional concentration meters, such as nuclear‑based and tuning fork types, suffer from radiation safety concerns, frequent maintenance requirements, and slow response times. Pisonics’ PS7000 acoustic impedance density meter, employing a non‑contact probe and a Chirp algorithm, delivers high‑frequency, stable density measurements, ensuring precise control by the DCS system, thereby enhancing clean coal quality and reducing media consumption.

Salt Lake Potash Evaporative Crystallization

Density Measurement of Salt Lake Brine Potash Fertilizer Evaporation-Crystallization Solid-Bearing Two-Phase Flow

In the potash‑extraction process from salt‑lake brine, the highly corrosive chloride‑rich environment and complex multiphase flow patterns often cause conventional density meters to fail repeatedly. Pisonics’ PS7000 acoustic‑impedance concentration meter features a fully PTFE‑lined design and a ceramic probe, offering exceptional corrosion resistance and insensitivity to bubbles, crystals, and flash vaporization. This ensures stable density measurement in solid–liquid two‑phase flows, significantly enhancing both the plant’s economic efficiency and product quality.

Mine Tailings Backfilling and Grinding Circulation

Mine Tailings Backfill Stations and Grinding Circuit Density Measurement

In mine tailings‑filling stations and grinding circuits, density control of high‑concentration paste slurries is critical. Conventional instruments struggle to meet these requirements due to issues such as wear and sluggish response. Pisonics’ PS7000 employs non‑contact measurement, with a response time of less than one second and a ceramic probe life of up to five years, thereby completely eliminating problems of wear and blockage, improving metal recovery rates, and reducing energy consumption.
