Ultrasonic Acoustic Attenuation Slurry Density Meter

Dual-probe precise through-beam measurement · External clamp‑on, no drilling required · Retrofit for existing pipelines—measure immediately upon installation

Product Overview Product Overview

PS7010 Series Ultrasonic Acoustic Attenuation Slurry Density Meter is a non‑nuclear‑source online slurry density monitoring instrument developed by Xi’an Pisonics Information Technology Co., Ltd. (PISONICS) for typical applications such as “no‑drilling installation,” “retrofit of aging pipelines,” and “monitoring in explosion‑hazard areas.” The instrument employs a dual‑probe, one‑transmit‑one‑receive through‑beam measurement configuration, with the transmitting and receiving probes mounted on opposite sides of the pipeline. It continuously analyzes the energy attenuation of ultrasonic waves as they pass through the medium, accurately converting this data into slurry density and concentration values.

The PS7010 offers both a pipe‑section type (insertion contact) and an external clamp‑on type (clamp‑on, no drilling required). In particular, the external clamp‑on version requires no drilling, no hot work, and no shutdown, enabling online slurry density monitoring to overcome traditional installation barriers—this is also the PS7010’s unique advantage over reflective‑type instruments. Within its full measurement range, the meter delivers high‑precision continuous measurement with an accuracy of ±1% FS, serving a wide range of industries including chemical processing, salt production, sugar refining, papermaking, food brewing, and mine tailings management.

Measurement Principle How It Works

The acoustic attenuation principle is based on a simple yet reliable physical fact: as ultrasonic waves propagate through a slurry, solid particles absorb and scatter part of the acoustic energy, causing the signal strength at the receiving end to diminish.

The PS7010’s transmitting probe continuously emits ultrasonic pulses of a specific frequency into the slurry within the pipeline; the receiving probe, installed on the opposite side, in real time captures the transmitted signal after it has passed through the medium. The host unit compares the transmitted and received signal strengths, applying temperature compensation and algorithmic calibration to determine the slurry’s density/concentration value.

→ The higher the slurry concentration and the more solid particles present, the greater the acoustic attenuation, the weaker the received signal, and the higher the measured density.

Two Installation Methods · One Product Dual Installation Options

The PS7010, as a single model, supports two installation configurations, allowing customers to adapt to different site conditions without re‑selecting a new product:

✦ Purchase Recommendation: For new projects, permanent monitoring points, or processes with stringent accuracy requirements, the pipe‑section type is recommended; for retrofitting existing production lines, explosion‑hazard areas, temporary monitoring, or processes that cannot be shut down, the external clamp‑on type is preferred.

Typical Application Scenarios Typical Applications

• Chemical Industry / Fine Chemicals —online monitoring of acid and alkali solution concentrations, control of reactor discharge concentrations, measurement of catalyst slurry densities
• Salt Production / Potash Fertilizers —monitoring of saturated brine concentrations, density control of crystallization solutions, online metering of salt solution pipelines
• Sugar Refining / Papermaking —measurement of syrup/press juice concentrations, monitoring of black liquor/white liquor densities, control of starch slurry densities
• Food / Brewing —monitoring of fruit juice/concentrate densities, control of beer fermentation wort concentrations, measurement of dairy process concentrations
• Mining / Mineral Processing —density control of degassed ore feeds/discharges, monitoring of tailings slurry transport densities
• Explosion‑Hazard Areas / Retrofits —non‑hot‑work installation in flammable and explosive zones, online retrofit of aging pipelines, temporary or permanent monitoring of processes that cannot be stopped

Installation Conditions and Usage Notes Application Notes

To ensure measurement accuracy and long‑term stability, please observe the following conditions when using the PS7010:

• The slurry should not contain large amounts of free air bubbles (bubbles can significantly amplify acoustic attenuation errors); for bubbly processes, the PS7000 acoustic impedance series is recommended.
• For external clamp‑on installation, the pipe wall must be uniformly thick, made of a consistent material, and the inner wall should be bare (without linings such as PTFE or rubber); otherwise, the pipe‑section type is advised.
• For pipe‑section installation, a straight pipe section of ≥5D upstream and 2D downstream is recommended to ensure a stable flow field.
• If the medium temperature exceeds 80°C, select the high‑temperature model; for highly corrosive conditions, duplex stainless steel 2205 or custom‑designed probes are recommended.
