Comparison Between Jiwei Radar Level Transmitters and VEGA Radar Level Transmitters
1. Why Compare Jiwei Radar Level Transmitters and VEGA Radar Level Transmitters?
In radar level transmitter selection, VEGA has long been one of the most representative international brands, especially widely recognized in industries such as chemical, energy, environmental protection, food, cement, mining, and water treatment. For many engineering projects, VEGA radar level transmitters are often regarded as a benchmark for high-end radar instrumentation.
With the continuous advancement of Chinese instrumentation technology, more users are paying attention to high-end radar level transmitters manufactured in China. Among them, Shenzhen Jiwei Automations Ltd.’s JWrada® radar level transmitters, featuring 80GHz high-frequency radar, FMCW measurement technology, self-developed algorithms, Bluetooth APP commissioning, local fast service, and competitive cost performance, have become one of the most notable radar solutions from China.
Therefore, under the growing demand for localized supply, cost reduction, shorter delivery cycles, and localized service support, many users ask: Can Jiwei radar level transmitters replace VEGA radar level transmitters? What are the differences and advantages of each?
2. Frequency Comparison: 80GHz Has Become the Mainstream Direction of High-End Radar
From a technological development perspective, 80GHz high-frequency radar has become a key direction in radar level and radar material measurement. Compared with traditional low-frequency radar, 80GHz radar provides a narrower beam angle, more concentrated energy, and better ability to avoid tank walls, brackets, agitators, inlets, and other interference objects.
VEGA radar products also widely adopt 80GHz technology in high-end models, while still offering 24GHz and other frequency options. Jiwei JWrada® radar level transmitters also adopt 80GHz as the mainstream solution, making them more suitable for complex storage tanks, narrow installation spaces, powder silos, liquid tanks, and various industrial environments.
For users, the core value of 80GHz radar lies in: more focused measurement, smaller beam angle, stronger anti-interference capability, and better installation flexibility. Especially in tanks with complex structures or poor installation conditions, 80GHz radar provides more stable echo detection.
3. Measurement Principle Comparison: FMCW as the Core Technology of High-End Radar
Both Jiwei JWrada® radar level transmitters and VEGA high-end radar products adopt FMCW (Frequency Modulated Continuous Wave) technology. FMCW radar transmits continuously varying frequency signals and calculates distance based on frequency differences between transmitted and reflected signals.
Compared with traditional pulse radar, FMCW radar offers higher resolution, better signal processing capability, and stronger performance in complex echo environments. It is widely used in high-precision liquid level and solid material level measurement applications.
Jiwei JWrada® combines FMCW technology with self-developed echo processing algorithms, optimized for dust, steam, foam, agitation, buildup, false echoes, and other complex industrial conditions. For Chinese radar manufacturers, algorithm capability is a key factor in entering high-end industrial markets.
4. Range and Accuracy Comparison: Application Fit Matters Most
In radar level transmitter selection, range and accuracy are key parameters. VEGA high-end radar models typically cover a wide measurement range from several meters to over 100 meters. Jiwei JWrada® radar level transmitters also support ranges from 30m to 120m, meeting most industrial liquid and solid level measurement requirements.
In terms of accuracy, high-end radar devices generally achieve millimeter-level precision. VEGA models typically achieve around ±1–2mm accuracy, while Jiwei JWrada® radar level transmitters also reach ±1–2mm accuracy levels.
However, real-world performance depends not only on specifications but also on process conditions such as medium reflectivity, tank structure, installation position, dust density, steam intensity, foam conditions, inflow impact, and commissioning quality.
5. Beam Angle Comparison: Narrow Beam for Complex Applications
Beam angle is a critical parameter in radar level transmitters. A smaller beam angle results in better signal focus and reduced interference from tank walls and internal structures.
VEGA 80GHz radar products are well-known for their mature narrow-beam design. Jiwei JWrada® 80GHz radar transmitters also feature approximately a 3° narrow beam angle, making them suitable for small tanks, narrow vessels, powder silos, and high installation positions.
In environments with agitators, ladders, inlets, inclined surfaces, or structural interference, narrow-beam radar significantly improves measurement stability.
6. Anti-Interference Capability: Jiwei Focuses on Adaptive Algorithms
In real industrial environments, radar level transmitters often face interference such as foam, steam, dust, material buildup, or internal structures causing false echoes.
VEGA has strong application experience in complex industrial environments. Jiwei JWrada® radar transmitters focus on 80GHz high-frequency radar combined with self-developed echo algorithms and intelligent signal processing.
Jiwei systems use adaptive algorithms to improve echo recognition accuracy, distinguishing real level signals from interference signals, significantly improving stability in dust, steam, and foam applications.
7. Commissioning Method Comparison: Bluetooth APP Advantage of Jiwei JWrada®
Traditional high-end radar transmitters often rely on handheld terminals or dedicated configuration software. VEGA provides mature tools, but learning complexity and field operation may still be relatively high for some users.
Jiwei JWrada® radar level transmitters emphasize ease of use and intelligence. They integrate Bluetooth connectivity, a mobile APP, LCD display, and physical button control.
Users can configure parameters via smartphone APP or directly on the device. In many cases, parameters can be pre-configured at the factory based on user requirements, allowing plug-and-play operation on site.
For batch projects, JWrada® also supports parameter copying from one device to multiple devices, significantly improving commissioning efficiency.
8. Remote Support Comparison: Local Responsiveness Advantage
International brands offer strong global systems, but Chinese manufacturers often provide faster response, shorter delivery cycles, and more flexible communication.
Jiwei JWrada® provides remote technical support via Bluetooth APP and engineering assistance, enabling real-time troubleshooting, parameter optimization, and echo analysis. This is especially valuable for overseas projects involving Chinese engineering teams.
In addition, Jiwei offers flexible customization, faster communication, and shorter lead times, making it highly suitable for time-sensitive projects.
9. Cost and Delivery Comparison: Chinese High-End Radar with Better Overall Value
VEGA products offer strong brand recognition and proven performance but generally come with higher cost and longer delivery times.
Jiwei JWrada® radar level transmitters provide high-end performance while maintaining more competitive pricing and shorter delivery cycles. For cost-sensitive projects, batch applications, and system integration projects, Jiwei offers a more balanced overall solution.
Users should evaluate not only unit price but also installation cost, commissioning cost, maintenance cost, and long-term lifecycle cost.
10. Which Users Are Suitable for Jiwei Radar Level Transmitters?
If a project previously uses VEGA, E+H, or Emerson radar transmitters and is considering a Chinese alternative, Jiwei JWrada® is worth evaluating.
Jiwei radar level transmitters are suitable for users requiring high precision, stability, and intelligent operation:
- Industrial automation factories (chemical, petrochemical, power, metallurgy)
- Water treatment and municipal engineering projects
- Powder and bulk solid industries (cement, mining, coal, grain)
- Energy and mining industries
- System integrators and engineering companies
- Export-oriented industrial projects
11. Jiwei or VEGA: How to Choose?
If the project requires a balance between performance, cost, delivery time, and service, Jiwei JWrada® is a strong candidate.
VEGA represents a mature international high-end radar solution. Jiwei JWrada® represents the fast-developing direction of high-end radar technology in China.
Both can be used for high-end industrial applications. The choice depends on budget, delivery requirements, service expectations, and localization strategy.
12. Conclusion: Chinese High-End Radar Is Approaching International Level
