Overview

Fine and bulk chemicals span large volumes of acidic, alkaline and organic concentration control. From reactor monitoring through absorption-tower metering to intermediate dosing tanks, accurate online density / concentration data is essential. Media are often highly corrosive, flammable or toxic — strict intrinsic-safety, wetted material and sealing requirements apply.

Typical challenges

  • Aggressive media (HNO₃, HCl, HF) need specialty wetted materials (Hastelloy C-276, tantalum, PFA)
  • Hazardous-area certifications: ATEX / IECEx, Ex d or Ex ia
  • Wide reaction temperature swings demand auto-compensation
  • Batch production calls for rapid model switching

PS7000

Slury density meter

The PS7000 series ultrasonic acoustic‑impedance slurry density meter completely eliminates the radiation safety risks and cumbersome environmental‑approval maintenance costs associated with conventional gamma‑ray density meters. By employing an innovative chirp acoustic‑impedance analysis algorithm, it overcomes measurement blind spots in complex operating conditions, enabling high‑precision continuous measurement.
PS7010

Acoustic attenuation density meter

The PS7010 series ultrasonic acoustic-attenuation slurry density meter employs a dual-probe through-beam measurement configuration, addressing the challenges of retrofitting aging pipelines and monitoring in hazardous‑area environments. The instrument leverages the energy attenuation of ultrasonic waves as they propagate through the slurry to accurately determine the slurry’s density and concentration, making it ideal for industries such as chemical processing, sugar refining, and mining.
PS7020

Sound Velocity Concentration Meter

The PS7020 series ultrasonic sound-velocity concentration/density meter measures the time of flight of ultrasonic waves in a liquid, and—combined with temperature compensation and an extensive library of calibration curves—converts this data in real time to yield the medium’s concentration and density, addressing the low accuracy and susceptibility to interference inherent in conventional measurement methods. Leveraging the fundamental physical principles of the sound-velocity method, this instrument is entirely immune to the effects of liquid color, transparency, electrical conductivity, vibration, noise, and flow velocity, thereby guaranteeing high precision and exceptional stability.
PS7400

Online tuning fork density meter

The PS7400 series online tuning fork density meter monitors liquid density in real time by leveraging piezoelectric excitation and changes in the tuning fork’s resonant frequency, requiring no maintenance while delivering highly accurate, repeatable measurements. Its built-in PT1000 temperature compensation eliminates drift due to temperature variations, making it suitable for diverse industrial applications such as pipelines and storage tanks, and widely used in the petrochemical, chemical, and pharmaceutical industries.
PS7200

Coriolis density meter

The PS7210 density meter employs the Coriolis force principle and achieves high‑precision, long‑term stability with no sensor drift through pure‑physical frequency measurement. It is suitable for continuous online monitoring of a wide range of liquids, including those in the petrochemical, brewing, and chemical industries—covering acids and alkalis—and supports installation in bypass lines or buffer tanks.
PS7110

Refractive concentration meter

The PS7110 series online refractive concentration meter uses high-resolution spectral acquisition and temperature-compensation algorithms to accurately convert the refractive index of a liquid into concentration, making it suitable for a wide range of industrial processes. Based on the principle of the critical angle of total internal reflection, the instrument features no moving parts and requires no reagents or consumables; it is unaffected by bubbles, color, or turbidity, ensuring long-term stability and maintenance-free operation.
PS7100

Spectroscopic concentration meter

The PS7100 series spectral concentration/density meter employs multi-channel full-spectrum technology to deliver real-time, reagent-free, and undiluted high-precision concentration measurements. Based on the Lambert–Beer law, this instrument provides broad coverage across the ultraviolet, visible, and near-infrared spectra, making it suitable for industries such as chemicals, pharmaceuticals, and food & beverage, and particularly well‑suited for concentration monitoring in complex multiphase systems.
PS7600

Microwave concentration/density meter

The PS7600 series online microwave density meter accurately captures the phase shift and amplitude attenuation of microwaves in the medium, thereby providing real-time measurements of slurry concentration, density, and moisture content. Employing a non‑nuclear, zero‑radiation microwave phase‑shift method coupled with Pt‑100 temperature compensation, it is ideally suited for challenging applications such as flue‑gas desulfurization in thermal power plants and coal‑washing slurries.
PS7300

Pipeline Differential Pressure Density Meter

Online differential pressure density meter uses a special density sensor to measure the density of various liquids or liquid mixtures online, directly reads the density value and outputs a 4-20mA DC signal with HART communication protocol. It is widely
