1. Overview

The SLDL5250 Series SoltaSmart Split-Type Radar Level Gauge/Level Difference Gauge/Open Channel Flow Meter is a high-performance industrial measuring instrument independently developed by SOLIDAT, integrating advanced Frequency Modulated Continuous Wave (FMCW) technology and proprietary SoltaSmart echo processing algorithm.Designed for the diverse measurement needs of modern industrial production, the product supports single-probe measurement of liquid level, distance and open channel flow, as well as dual-probe high-precision level difference measurement, and is widely applicable to solid and liquid medium measurement in various industrial fields. With strong anti-interference, high environmental adaptability and simple operation, it has become a reliable choice for industrial process monitoring and control.

2. Working Principle

Based on the mature FMCW (Frequency Modulated Continuous Wave) working principle, the SLDL5250 series instrument transmits a linear frequency-modulated continuous wave signal that sweeps stably within the working frequency band. When the signal encounters the measured medium surface (solid/liquid) or channel boundary, it is reflected to form a reflected wave.

The instrument's high-speed processing module real-time compares the frequency difference △f between the original transmitted wave and the reflected wave, and converts the frequency difference into a precise distance value through professional algorithm calculation. According to the actual application configuration, the measured data is further converted into liquid level, level difference or open channel flow data that meets industrial application standards, and is output through multiple signal channels for on-site display and remote control system access.

Single-probe configuration: Realizes accurate measurement of medium distance, liquid level height and open channel flow rate/flow volume

Dual-probe configuration: Achieves high-precision measurement of level difference and average level value between two measuring points

3. Core Product Features

3.1 Advanced Core Technology & Strong Adaptability

Equipped with a high-performance advanced microprocessor and proprietary SoltaSmart echo processing technology, the instrument can effectively identify and process echo signals in complex working conditions such as uneven medium surface, strong turbulence and multiple obstacles, ensuring stable and accurate measurement results.

3.2 Flexible Sensor Frequency Selection

Optional 80GHz or 120GHz high-frequency sensor; different frequency sensors can be selected according to the actual application scenarios (such as measurement range, medium type, environmental interference), meeting the personalized measurement needs of different industrial fields.

3.3 Super Strong Penetration & Anti-interference

The high-frequency radar signal has strong penetration capability, which can effectively penetrate high steam, high dust, smoke and other harsh environmental media, and is especially suitable for high steam and high dust working conditions such as chemical plants, smelters, grain depots and sewage treatment plants.

3.4 Easy Debugging & Time-saving Operation

Supports on-site non-stop debugging, no need to fill or empty the measured container/channel during debugging and calibration, avoiding the impact of debugging on industrial production processes and greatly saving on-site operation and maintenance time.

3.5 Intelligent False Echo Elimination

Built-in "False Echo Learning" intelligent function; the instrument can automatically learn and record the characteristic signals of multiple false echoes generated by tank walls, flanges, brackets and other structures, and accurately lock the real echo signal of the measured medium, ensuring measurement accuracy under complex structural conditions.

3.6 Humanized Operation & Maintenance Design

Supports multi-language operation interface (including Chinese and English), adapting to the operation habits of technicians in different countries and regions

With real-time echo and false echo display function, the on-site debugging personnel can visually view the signal waveform and characteristic data, facilitating rapid fault analysis, parameter adjustment and daily maintenance.

3.7 High Protection Grade & Durable Use

The probe and controller are designed with high protection performance, with IP68 high protection grade, which can resist long-term immersion, dust accumulation, rain and snow erosion, and is suitable for harsh industrial on-site environmental use, effectively extending the service life of the instrument.

3.8 Rich Communication & Signal Output Modes

Fully compatible with industrial mainstream communication protocols and signal output modes, supporting HART, Modbus, Profibus PA, Foundation Fieldbus, AUTBUS bus, as well as GPRS/CDMA remote wireless communication and Bluetooth local communication; easy to connect with DCS, PLC and other industrial control systems, realizing on-site and remote data transmission and control.

3.9 Multi-functional & Multi-scenario Application

Integrating multiple measurement functions in one machine, it is applicable to solid and liquid medium level measurement, multi-point level difference and average level measurement, and professional open channel flow measurement; it can be widely used in petroleum, chemical, electric power, metallurgy, water treatment, grain and oil, building materials and other industrial fields.

3.10 Stable Performance & Reliable Quality

Strictly in accordance with international industrial production standards for R&D and production, with stable process pressure and temperature adaptability, and passed a number of international authoritative certifications, ensuring the reliability and stability of long-term continuous operation in industrial environments.
