Jiwei JWrada®-35 | 80GHz Radar Level Meter for Coke Silo
Introduction
In the metallurgical, coking, and chemical industries, effective coke storage and handling management is critical to production safety and efficiency. Coke is dry, dusty, and hard-granulated, creating extremely harsh conditions inside silos. Conventional ultrasonic and contact-type capacitive level instruments often fail under these circumstances due to dust absorption, probe wear, or unstable signals.
To address these challenges, Jiwei Automations has launched the next-generation high-performance radar level meter—JWrada®-35. Based on 80GHz high-frequency FMCW continuous-wave radar technology, it features a proprietary hardware design and self-developed signal algorithm system, offering a more compact form factor for flexible installation and real-time algorithm updates to maintain leading-edge performance under varying operating conditions.

Challenges of Coke Silo Level Measurement
Coke silos are typically tall, with high dust concentrations and abrasive media, placing stringent demands on level measurement:
High Dust Environment Causing Signal Attenuation
During filling or discharge, friction between coke particles generates dense dust that interferes with ultrasonic or optical signals, causing conventional measurement devices to fail.
Abrasive Particles Causing Probe Wear
Hard coke granules severely wear contact-type probes, shortening instrument service life.
Extreme Temperature and Pressure Fluctuations
Coke silos often contain high-temperature gases and negative pressure, causing some sensors to drift or lose accuracy.
Dynamic Material Flow Disturbance
Impact from falling material and surface fluctuations generate false echoes, making it difficult for traditional radar instruments to reliably track the real material level.
Jiwei Solution: JWrada®-35 Radar Level Meter
To tackle the challenges of high dust concentration, abrasive media, and large temperature variations inside coke silos, Jiwei Automations leverages its deep expertise in radar measurement technology to provide the high-performance JWrada®-35 Radar Level Meter.
Based on a proprietary hardware platform and self-developed software algorithms, it supports dynamic algorithm updates and continuously optimizes signal processing for different operating conditions, ensuring stable and continuous level measurement even under dust, temperature fluctuations, or high-pressure environments.

Key Features
Proprietary Mold Design for Compact and Flexible Installation
The JWrada®-35 is independently designed and molded by Jiwei, with a smaller footprint than standard radar devices, allowing flexible installation in space-constrained silos or equipment.
Self-Developed Algorithm, Continuously Optimized
Jiwei’s proprietary software platform supports online upgrades, allowing real-time optimization of algorithms according to site conditions. This ensures signal processing logic stays at the forefront of technology. In contrast, OEM radar products from other manufacturers are fixed and cannot be upgraded.
80GHz High-Frequency FMCW Radar Technology
With a narrow beam angle of just 3°, signals are highly focused, effectively avoiding interference from silo walls or support structures for more accurate level detection.
Non-Contact Measurement for Maintenance-Free Operation
The measurement process does not contact the coke medium, effectively preventing wear and adhesion, ensuring long-term stable operation without additional maintenance.
Wide Operating Range
Suitable for temperatures from −40℃ to +220℃ and pressures from −1 to 40 bar, enabling stable performance in high-temperature, high-pressure, or dusty environments.
High Accuracy and Ultra-Long Range
Measurement range up to 150 meters with ±1 mm accuracy, suitable for large silos, tanks, and coke transport systems.
Wireless Commissioning and Remote Diagnostics
Equipped with an optional Bluetooth module, it supports wireless commissioning, parameter setting, and remote echo curve viewing via the Jiwei Smart Control app, enhancing intelligent on-site operation and maintenance.
Working Principle
The JWrada®-35 emits 80GHz FMCW radar waves and receives signals reflected from the material surface. By calculating the frequency difference between transmitted and received waves, the system determines precise distances.
Radar waves are unaffected by dust, temperature, or gas density, ensuring stable and reliable measurements. Jiwei’s proprietary algorithms automatically identify false echoes and effectively filter out interference from material flow and dust.
Advantages of JWrada®-35 in Coke Silos
- Strong Dust Resistance
Proprietary algorithms combined with narrow-beam antennas maintain stable signal output even in dense dust, fully resolving signal interruptions during loading. - Long Service Life
Non-contact measurement avoids abrasive wear. With IP68 protection and high-temperature sealing, it operates reliably in harsh conditions. - Low Maintenance Cost
No need for regular cleaning or probe replacement, reducing maintenance costs and downtime risks. - Simple Installation and Commissioning
Compact design allows direct replacement of conventional radar devices without modifying the installation port. Bluetooth commissioning significantly improves setup efficiency. - Sustainable Technological Upgrades
The software platform supports remote updates, enabling Jiwei to continuously deliver algorithm enhancements and keeping the device technologically “always new.”
Typical Application Case
At a large steel group’s coking workshop in East China, six vertical coke silos over 30 meters high operate in high-temperature, high-dust, and corrosive gas environments. Dust from falling coke accumulates on radar probes, and material surface fluctuations cause signal drift, echo loss, and range jumps with conventional imported radar meters. Unstable measurement sometimes triggers incorrect discharge gate operation, affecting production.
Replacing the old devices with Jiwei JWrada®-35, technicians leveraged its compact design and standard flange interface for fast installation without altering mounting holes. Using the Jiwei Smart Control app via Bluetooth, the adaptive algorithm mode dynamically analyzed signal features, recognizing surface echoes and suppressing noise.
After two weeks of validation, level signal stability improved by over 70%, with clear echo curves and almost no abnormal jumps. Even at dust concentrations up to 400 mg/m³, the meter output smooth, continuous readings.
After six months, the device required no maintenance, probe surfaces remained clean, and customers reported stable level control, significantly improved discharge accuracy, and approximately 15% increased coke transport efficiency. The site engineer commented:
“Compared with previous imported brands, JWrada®-35 is easier to install and maintain, with flexible algorithm adjustment. Its software continuously adapts to field conditions, which is remarkable.”
This case demonstrates the outstanding performance of JWrada®-35 in high-dust environments and validates Jiwei’s proprietary algorithms and hardware platform in the coking industry.
