Radar Level Meter Review: Brand Comparison

In today’s era of intelligent manufacturing and upgrading process industries, liquid level measurement plays a crucial role in ensuring process stability and safety. Especially in industries such as chemical, power, metallurgy, pharmaceutical, food, and environmental protection, there is an increasing demand for non-contact, high-precision, and interference-resistant level measurement instruments. Radar level meters have become the mainstream technology in level measurement due to their narrow beam angle, high accuracy, and ease of installation and maintenance.

Currently, the market is flooded with numerous brands and rapid technological advancements, with domestic brands gaining notable momentum. This article compares the main radar level meter brands, analyzing their technical specifications and application capabilities, with a focused evaluation of Jiwei’s JWrada-31 radar level meter, providing an authoritative reference for product selection.

Comparison of Mainstream Radar Level Meter Brands

The leading brands in the market include Germany’s VEGA, Endress+Hauser (E+H), Siemens, ABB, and the leading domestic brand Jiwei Automation. We compare the following representative 80GHz radar level meters:

Brand & Model	Frequency Range	Accuracy	Communication	Antenna Type	Typical Applications
VEGA VEGAPULS 64	80GHz	±1 mm	4-20mA / HART / Profibus	Horn Antenna	Powder, liquids, corrosive media
E+H FMR62	80GHz	±1 mm	HART / FF / PROFIBUS	PTFE Horn / Rod Antenna	High temperature & pressure tanks, safety-critical environments
Siemens LR110	80GHz	±2 mm	Modbus / 4-20mA	Plastic Lens Antenna	Compact tanks, sewage pits
ABB LVRD500	80GHz	±1 mm	HART / Modbus	Waveguide / Rod Antenna	Food-grade, chemical tanks
Jiwei JWrada-31	80GHz	±1 mm	4-20mA / HART + Bluetooth	316L + PTFE Lens Antenna	Harsh corrosion, high dust, agitation, tall tanks

From the comparison, while foreign brands have mature technology, they often come with high prices, long delivery times, and slower after-sales support. Jiwei’s JWrada-31, leveraging domestic R&D capabilities, competes on a par with these platforms and offers advantages in user experience and industry adaptability.

JWrada-31 Excels in Challenging Conditions: Dust, Steam, and Agitation

Technical Advantages of JWrada-31 Radar Level Meter

1. High Frequency, Strong Focus, Superior Penetration

JWrada-31 adopts 80GHz Frequency Modulated Continuous Wave (FMCW) radar technology with a narrow 3° beam angle. Compared to older 26GHz products, it reduces multipath interference significantly, enhancing measurement stability, especially under:

• High dust environments (e.g., cement, lime, ore silos)
• Severe steam interference (e.g., food heating kettles, pharmaceutical fermentation tanks)
• Stirred media (e.g., agitation kettles, reaction vessels)

2. Proprietary Algorithm Suppressing False Echoes

Jiwei’s proprietary intelligent echo recognition technology automatically filters wall reflections, agitator echoes, and buildup echoes, focusing on valid signals to ensure reliable measurements, eliminating false readings, jumps, and dropouts.

3. Bluetooth Debugging via “Jiwei Smart Control” Mini Program

Unlike traditional tuning methods relying on HART handheld devices or PC software, JWrada-31 supports one-click debugging via mobile Bluetooth. Users can download the “Jiwei Smart Control” WeChat mini program to:

• Quickly connect devices and set parameters
• View real-time liquid level trend charts
• Perform fault diagnostics and maintenance alerts
• Manage multiple devices efficiently

4. Robust Anti-Corrosion Design and Customization

The JWrada series offers multiple corrosion-resistant antenna materials (PP/PTFE) suitable for measuring strong corrosive media like hydrochloric acid, sulfuric acid, and sodium hydroxide. Custom explosion-proof and splash-proof structures are available to meet special requirements in petrochemical and pharmaceutical industries.

5. Comprehensive Certifications Ensuring Safety and Reliability

• Explosion-proof certification (Ex ia IIC T6 Ga) for hazardous environments
• CE certification for seamless export
• Industrial protection rating IP67 for dust and water resistance

Typical Industry Applications

Case 1: High-Dust Cement Silo Measurement
A large cement plant originally used an ultrasonic level meter to measure raw material silo levels. Due to heavy dust and tall silo height, signal loss was frequent. After replacing it with JWrada-31, stable measurement was achieved via high-frequency beam and smart filtering algorithms, improving accuracy by 30% and reducing blind zone to 0 cm.

Case 2: Corrosive Acid Tank Monitoring in Chemical Plants
A chemical plant in Jiangsu stored concentrated hydrochloric acid in PTFE-lined tanks. Traditional level meters failed frequently due to corrosion. The JWrada-31 with fully sealed corrosion-resistant waveguide antenna ran reliably for extended periods, significantly reducing maintenance costs and improving operational reliability.

Case 3: Food Industry Agitation Vessel Level Control
In a dairy processing plant, high-temperature agitation and steam interference affected level measurement in reaction tanks. JWrada-31 equipped with short antenna and agitation compensation algorithm accurately tracked liquid levels while meeting food-grade material standards, with successful replication in similar plants.

Customer Feedback and Market Recognition

Users widely praise JWrada-31 for its ease of debugging, signal stability, and rapid domestic support. Sample feedback includes:

• “We previously used a German brand but found maintenance and debugging complicated. Jiwei’s radar level meter is easier to debug, highly accurate, and the local after-sales service is reliable — great value for money.” — Technical Manager, Large Chemical Company
• “Using the ‘Jiwei Smart Control’ mini program, we can debug with a phone, which is very convenient for frontline technicians.” — Instrument Maintenance Engineer, Water Treatment Plant

Conclusion: A Cost-Effective Domestic Choice for Radar Level Measurement

Amid a market dominated by imported brands, Jiwei’s JWrada-31 radar level meter stands out through localized design, advanced beam technology, intelligent debugging, and excellent resistance to interference and corrosion. It meets conventional tank level measurement needs and excels in challenging environments such as high dust, strong agitation, and severe corrosion. It is a top choice for enterprises pursuing domestic substitution of radar level measurement equipment.
