Independent Third-Party Validation Confirms the High Performance of Jiwei’s Mini Radar Level Meter
As level-measurement technologies continue to advance toward higher accuracy, smaller form factors, and smarter signal processing, the Mini Radar Level Meter from Shenzhen Jiwei Automations Ltd. has rapidly gained attention across multiple industries. To obtain an objective and comprehensive evaluation prior to procurement, a prospective customer voluntarily commissioned a professional third-party laboratory to perform full-range interferometer comparison tests and calibration analysis.
The results showed that the Mini Radar Level Meter not only excels in accuracy and linearity but also demonstrates significantly better stability than the average level of similar products in the market.
Full-Range Interferometer Testing: Accuracy Verified up to 28m
Using a precision interferometer as the reference standard, the Mini Radar Level Meter was tested continuously from zero distance up to over 26 meters.
- Measured deviation: 0–49.11 mm
- Maximum test distance: ~28.014 m
- Max deviation percentage: only 0.76%
- Average deviation percentage: approx. 0.24%, far below industry requirements
For a compact, low-power 80GHz radar sensor, this performance matches or even surpasses certain higher-priced alternatives in the market. Whether in short-range fine variations or long-range weak-echo conditions, the Mini Radar Level Meter maintained a stable, drift-free and jump-free output throughout the test.
Comparison with Competitors: Clear Performance Gap
The customer also tested competing products under the same setup. Results revealed:
- Competitor deviation at long range (20m+): 5–12 cm
- Competitor average deviation percentage: 0.8%–1.2%, significantly higher than Jiwei’s 0.24%
- Competitors showed jumpy output and occasional drift under weak echo or small-range variation
- Jiwei Mini Radar Level Meter maintained a smooth and continuous curve
Why the Difference? Key Technical Advantages
1. Proprietary Algorithms & Superior Anti-Interference
The Mini Radar Level Meter uses Jiwei’s self-developed signal-processing algorithm (software copyright filed), featuring:
- High-precision echo analysis
- Advanced signal filtering
- Robust suppression of multipath reflections, pipe vibrations, foam, bubbles, and viscous media
Many competing products are more susceptible to drift or instability under such challenging conditions.
2. Precision-Designed 80GHz Antenna
A tightly focused, high-directionality antenna ensures high signal-to-noise ratio even in weak-echo environments.
3. Compact, Low-Power Hardware Architecture
Optimized internal integration reduces electronic noise and minimizes system drift, enhancing long-term stability.
Linear Calibration Analysis: Outstanding Linearity Across the Full Range
A full-range linear regression analysis further validated measurement consistency:
True Distance = 0.9986 × Measured Value − 1548.03
- The slope 0.9986 is extremely close to 1, indicating negligible scale deviation
- The intercept matches the recorded initial offset almost exactly
- Confirms that the primary error originates from initial zero-point offset, not nonlinear distortion
This proves the product maintains excellent linearity across the entire measurement span.
Advanced 80GHz FMCW Technology with Strong Signal Integrity
Using 80GHz FMCW radar, the device offers:
- Narrow beam angle
- High spatial resolution
- Reliable target recognition under steam, foam, turbulence, or weak echo
- FFT spectral analysis for precise time-delay calculation
The entire signal chain is optimized for high stability, rapid response, and strong anti-interference performance.
High Accuracy + Long Range + Compact Size
The Mini Radar Level Meter achieves:
- ±1 mm accuracy
- Up to 30 m measuring range
- Ideal for both large-scale hydrology monitoring and compact industrial tank applications
It includes a simple local display, supports HART / Modbus, and integrates Bluetooth 5.0 for wireless configuration via the Jiwei Smart Control® app. With cloud connectivity, it enables remote configuration, remote upgrades, and remote monitoring.
AI-Enhanced Echo Learning for Long-Term Stability
Equipped with Jiwei’s intelligent echo-learning algorithm, the device offers:
- False-echo suppression
- Multi-layer echo separation
- Dynamic tracking for changing conditions
Its lightweight, UV-resistant nylon enclosure (optional metal version) is certified IP66/67 and IP68, operating reliably from –40℃ to 80℃. Installation options include G1½ thread or mounting bracket, with 2-wire 4–20mA/HART or 4-wire RS485/Modbus outputs.
A Strong Alternative to Ultrasonic Level Meters—Especially in Water & Hydrology
With proven stability and cost-effectiveness, the Mini Radar Level Meter is increasingly chosen as a replacement for ultrasonic meters. It is particularly well-suited for:
- River level monitoring
- Open-channel water measurement
- Wastewater treatment
- Reservoir & sluice management
- Municipal drainage & flood warning systems
Conclusion: High Performance Proven by Real Independent Testing
The customer-funded testing and calibration confirm that the Mini Radar Level Meter is not just a product with impressive specifications—it is a high-frequency radar instrument proven to deliver reliable, high-quality data in real applications.
It represents the growing technical strength and global competitiveness of modern radar-measurement solutions developed by Shenzhen Jiwei Automations Ltd.
