94 Jiwei JWrada® Radar Level Meters Deployed in Ningbo Fine Chemicals Project
— Empowering Complex Level Monitoring with Proprietary Algorithms and Lightweight Design
Project Overview: Domestic High-End Instruments Gain Trust
Recently, 94 Jiwei JWrada® radar level meters were successfully delivered and put into operation at a fine chemicals manufacturer in Ningbo. The project covers critical process units, including reactors, storage tanks, and solvent intermediate tanks, where high stability and anti-interference capability for level measurement are essential.
During the project’s initial phase, the client conducted on-site comparisons of multiple brands, evaluating signal consistency, blind zone coverage, and system response speed. The JWrada®-31 80 GHz radar level meters from Jiwei Automations stood out with their proprietary software algorithms, lightweight structural design, and excellent environmental adaptability, demonstrating stable and reliable performance under complex process conditions, ultimately earning the client’s approval.
Technical Highlights: Full-Chain In-House Development Ensures a Complete Engineering Loop
Compared with traditional 26 GHz radar, the JWrada® Radar Level Meter series features smaller antenna apertures and higher energy focusing, significantly improving echo signal recognition. Its self-developed signal processing algorithms can separate valid echoes from steam, foam, and multi-reflection environments, enabling continuous and stable level tracking. Weighing only about 1.5 kg, the devices are easier to install and maintain than similar market products.
Jiwei’s R&D team revealed that the JWrada® radar level meter is entirely in-house designed—from the RF antenna, signal modulation unit, transmit/receive modules, main control PCB, to system software and signal algorithms. The device undergoes full modeling, simulation (S-parameter extraction, coupling efficiency analysis), prototyping, and vector network analyzer testing, forming a complete engineering loop that ensures reliable high-frequency, high-speed signal transmission. This comprehensive self-developed approach maintains leading performance in signal integrity, power efficiency, and system stability.
Operational Performance: Stable in High-Temperature, Corrosive Environments
Some storage tanks at the Ningbo site operate under high-temperature, high-humidity, and corrosive gas conditions. Traditional level meters often experience signal drift or antenna condensation in such environments. JWrada®, leveraging independently optimized waveguide structures and signal compensation algorithms, delivers stable continuous waveforms, providing reliable data for process control.
An instrumentation engineer involved in the project commented: “Previously, similar radar meters were highly affected by steam and required frequent manual calibration. Now, Jiwei’s devices are much more stable; once installed, they rarely need intervention.”
Smart Operation: Mobile App Enables Easy Tank Monitoring
Throughout the project, Jiwei’s engineering service team participated in installation guidance, initial calibration, and system commissioning, ensuring each meter operated at optimal performance. Since commissioning, the devices have run smoothly, with continuous and reliable monitoring data.
To enhance user experience, a mobile-level management app was deployed for the project. On-site personnel can view tank level data in real time, receive alarm notifications, and monitor device status.
“One swipe on the phone shows all tank levels, device runtime, and alarm status. Previously, we had to climb tanks to check. Now we can monitor everything from the control room or even offsite—it’s really convenient,” said a maintenance staff member.
Industry Significance: Engineering Breakthrough for Domestic High-Frequency Radar
The project’s success further strengthened the client’s trust in domestic instruments. Project manager Jiang stated that Jiwei’s team demonstrated excellent coordination from installation to system integration, and the devices withstood continuous production conditions. He noted that as domestic chemical companies increasingly demand continuous monitoring and automation, breakthroughs in local algorithm and structural design are highly significant—not merely as an import substitute, but as a step toward building an independent technology system.
The successful deployment of Jiwei JWrada® radar level meters provides a reference for instrument upgrades in the Ningbo fine chemicals sector. As smart manufacturing progresses in China’s fine chemicals industry, more companies are prioritizing level monitoring stability and maintainability. Products like JWrada®, featuring self-diagnosis, lightweight design, and high reliability, are becoming essential for equipment upgrades and digital transformation initiatives.
