PS7010 Series
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,实时 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.
Core Technical Advantages Core Advantages

1 | Ultrasonic transmission measurement principle based on acoustic attenuation | With a dual-probe configuration—one transmitting and one receiving—the energy attenuation of ultrasonic waves after penetrating the slurry is directly correlated with density, offering a simple and reliable principle. |
2 | External-mount, hole-free installation | No need for drilling, hot work, or shutdown—deployment on the existing pipeline can be completed in just a few minutes |
3 | Pipe section / External dual-sensor solution | Insertion-type models offer higher accuracy, while clamp-on external-mount models provide greater installation convenience—choose freely based on your operating conditions. |
4 | Plug-and-play installation and removal | The external-mount type requires only steel band clamping and coupling agent application, enabling flexible deployment for both legacy pipeline retrofits and temporary monitoring points |
5 | Non-nuclear source, zero radiation | Completely bid farewell to the radiation hazards and environmental approval requirements of gamma-ray density meters—ensuring peace of mind and safety |

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:
Comparison Dimensions | Tubular-type (insertion-contact) | External clamp-on installation |
Probe and Slurry | Direct contact with the slurry | Measure through the pipe wall without contacting the medium |
Construction Requirements | Requires hole‑cutting, flange installation, or welding of a mounting base | No need for drilling, hot work, or shutdown |
Installation Difficulty | Medium (standard tube section flange connection) | Ultra‑simple (steel strip fixation + couplant) |
Tube Wall Requirements | No special requirements | Uniform thickness, liner-free, and made of a single material |
Detachable | Disassembly requires a shutdown and flange removal | Can be disassembled and the measurement point relocated at any time |
Measurement Accuracy | Higher (direct contact) | Slightly affected by the pipe wall (can be compensated and calibrated) |
Recommended Applications | New pipelines, permanent monitoring, various operating conditions | Explosion-proof areas, renovation of aging pipelines, temporary monitoring, and processes that cannot be shut down |
✦ 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

- 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.
