JWrada-22 80GHz Mini Radar Level Meter for Small Tank Measurement
In industrial process control, level measurement technologies for large storage tanks are already relatively mature. However, what truly troubles engineers are often small tanks with limited space, complex environments, and highly sensitive installation constraints.
Whether in semiconductor cleaning equipment, pharmaceutical and biochemical reactors, or buffer tanks in fine chemical processes, these applications impose extremely demanding requirements on level measurement instruments:
they must be compact enough to avoid internal agitators and obstacles, operate at high frequencies to penetrate vapor and condensation, and feature intelligent software capable of handling complex false echoes.
The JWrada®-22 80GHz high-frequency radar level meter from Jiwei Automations was developed precisely to redefine the standard for “mini radar” solutions.
JWrada®-22 80GHz High-Frequency Radar Level Meter
1. Core Hardware: Designed Specifically for Confined Spaces
The JWrada-22 is not simply a scaled-down radar; it is an industrial-grade sensor deeply optimized for small tank applications.
Ultra-narrow beam angle for interference avoidance
Using 80GHz FMCW (Frequency Modulated Continuous Wave) technology, the radar features an extremely narrow beam angle. In confined tank environments, the radar signal precisely avoids feed inlets, agitators, and internal structures, directly targeting the liquid surface.
Zero blind zone design
A common issue in small tank measurement is the inability to detect levels near the tank top. The MINI-22 optimizes antenna structure to achieve zero blind zone, ensuring high accuracy even when installed close to the tank roof, significantly improving usable tank capacity.
Integrated display module
Unlike many compact transmitters that sacrifice usability, the JWrada-22 features a built-in high-definition display, allowing operators to directly view real-time level, signal strength, and device status without external tools.
2. Software Defines Performance: The Invisible Core Advantage
If hardware forms the skeleton of radar, then self-developed software algorithms are the soul that differentiate JWrada® from other manufacturers.
As hardware becomes increasingly standardized, the ability to handle complex conditions depends entirely on algorithm capability.
1. Full lifecycle control: From configuration to diagnostics
The JWrada® software system covers all interaction stages of the device lifecycle.
Users can not only configure measurement ranges but also perform in-depth process tuning.
The built-in fault code system enables maintenance personnel to quickly identify issues such as antenna buildup, signal loss, or power faults—eliminating guesswork in troubleshooting.
2. Proprietary EFT Curve Analysis Technology
Jiwei’s independently developed EFT (Echo Filtering Technology) curve analysis is key to handling complex echoes in small tanks.
By digitally modeling real-time echo signals, the system can automatically identify and suppress false echoes caused by static obstacles.
- Echo Curve: Reflects real-time energy distribution inside the tank
- EFT Curve: Applies intelligent filtering to convert complex interference into clear, valid signals, ensuring stable readings even under turbulence or foam conditions
3. Cloud-Based Remote Collaboration
This is Jiwei’s leading advantage in the industry.
For remote or complex applications, JWrada® supports cloud-based remote commissioning:
- One-on-one remote support: Engineers can connect directly to field devices without traveling
- Real-time data access: Echo curves can be analyzed remotely for professional diagnostics
- Customized algorithm optimization: Engineers can remotely adjust parameters based on specific process conditions (e.g., dielectric constant, extreme temperature/pressure), ensuring optimal performance for each device
This integration of hardware and software makes JWrada-22 not just a device, but a complete level measurement solution system.
3. Application Case: Small Clean Water Tank Level Monitoring
Process Background
A food factory in Zhejiang uses a small clean water buffer tank in its production process. The tank has a diameter of approximately 500 mm and a height of about 1 meter.
Due to limited space and frequent level fluctuations, the previously used conventional level meter showed unstable readings at low levels, occasionally causing data fluctuations that affected operator judgment.
Solution
The customer selected the JWrada-22 mini radar level meter.
Its compact structure allowed direct installation on the existing small nozzle at the tank top, without any modification, enabling quick installation and commissioning.
Results
Stable measurement
Even at low liquid levels, the instrument maintained stable output, eliminating the “loss of measurement near bottom” issue.
Strong interference resistance
Radar measurement is unaffected by vapor or minor surface disturbances, ensuring consistent reliability.
Easy installation and maintenance
Compact design significantly reduces installation difficulty and minimizes maintenance requirements.
On-site visualization
The built-in display allows operators to directly read level values during inspection, improving efficiency.
Expert Comment
“In this type of simple yet space-constrained tank, the JWrada-22 not only installs easily but also delivers highly stable measurements, fully demonstrating the advantages of mini radar in small-range applications.”
