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.
Online Density Measurement for Limestone Slurry Preparation
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.
Online Density Measurement for the AFT Tower (High-Concentration Desulfurization Slurry Processing Tower)
In the AFT tower, measuring the density of high-concentration, high-viscosity, and easily crystallizing slurries has long been a challenge. The PS7000 acoustic impedance concentration meter, employing non-contact measurement, overcomes the failures of conventional instruments caused by clogging, wear, and crystallization, enabling real-time, continuous monitoring of slurry density and automated control of the discharge process, thereby ensuring stable system operation.
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.
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.
Typical Applications of Slurry Density Measurement in the Iron and Steel Metallurgy Industry
In the wet-slurry processing of the steel industry, conventional density meters frequently fail due to dust, bubbles, and abrasive particles. Pisonics’ PS7000 acoustic‑impedance concentration meter employs a ceramic probe and a Chirp algorithm to enable non‑contact measurement, which not only extends instrument life but also enhances data stability, significantly reducing maintenance costs and increasing iron recovery rates.
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 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.
