Product Advantages
The core value of the 26 GHz radar level gauge lies in its comprehensive performance enhancement enabled by “high-frequency” technology, perfectly addressing the pain points of traditional measurement methods.
1. Narrow Beam Angle, Strong Anti-Interference Capability: With an extremely small beam angle (typically ≤4°), energy is concentrated, effectively avoiding interference from tank obstacles (such as ladders, heating coils, and feed ports). This simplifies installation and ensures stable measurement.
2. Exceptional Dust and Vapor Penetration: Its high-frequency, short-wavelength characteristics maintain signal strength even in heavy dust or dense vapor conditions, effectively overcoming false echoes. Measurement reliability significantly outperforms low-frequency radar and ultrasonic systems.
3. Exceptional Measurement Accuracy: Utilizing FMCW technology, it achieves measurement accuracy of ±2mm. Even in large storage tanks, it delivers millimeter-level level measurement precision, meeting requirements for trade measurement and precise control.
4. Non-Contact Measurement, Maintenance-Free: The measurement process avoids contact with the medium, completely eliminating issues like corrosion, adhesion, and wear. It offers a long service life and truly achieves maintenance-free operation, reducing total cost of ownership.
5. Intelligent Echo Processing and Diagnostics: Built-in powerful echo processing software automatically identifies and locks onto true material echoes while effectively suppressing false echoes. Self-diagnostic capabilities provide early warnings for issues like antenna contamination or instrument malfunctions.
6. Safe, Eco-Friendly, and Versatile: Non-contact measurement ensures zero process contamination, meeting sanitary requirements. No process penetration is required, offering intrinsic safety for use in explosion-proof zones (Ex ia/ib).

Core Application Areas
✅ Petrochemical Industry: Trade settlement and inventory management for crude oil, refined oil storage tanks, asphalt, benzene compounds, and various intermediate raw material tanks.
✅ Chemical and Pharmaceutical: Level control for highly corrosive media (acids, alkalis, solvents), reactors, vacuum tanks, and high-temperature molten salt tanks.
✅ Water Treatment & Environmental Protection: Level and interface measurement for sewage tanks, slurry tanks, chemical dosing tanks, and clarification tanks.
✅ Food & Beverage: High-precision level control for sanitary-grade applications like syrup tanks, milk storage silos, and fermentation tanks.
✅ Energy & Power: Material level monitoring in high-dust environments such as fly ash silos, slurry ponds, and desulfurization towers at large coal-fired power plants.

Performance Parameters

• Measuring Technology: Utilizes FMCW (Frequency Modulated Continuous Wave) technology, offering advantages in accuracy and signal processing over pulsed radar.

• Measuring Range: 0 to 70 meters, covering most river, reservoir, and open channel applications.

• Measuring Accuracy: Up to ±3mm, suitable for high-precision water level monitoring.

• Beam Angle: ≤4° (typical). This narrow beam focuses energy, effectively avoiding interference from obstacles like bridge pillars or channel walls.

• Operating Frequency: 26 GHz. This high frequency is key to its strong anti-interference capability, high accuracy, and good penetration.

Installation & Adaptability

• Process Connection: Flexible options including G1-1/2″ thread or flange connections to suit different mounting brackets or pipes.

• Installation Advantage: The narrow beam angle allows for more flexible placement, simplifying installation by helping to avoid obstacles.

• Non-Contact Design: The sensor does not contact the water, eliminating maintenance work caused by flow erosion or corrosion, making it ideal for open channels.

 Environmental Adaptability

• Medium Temperature: Can measure media from -40°C to 100°C, adapting to cold regions and some high-temperature conditions.

• Explosion Proof Rating: Up to Exd/ia IIC T6 Ga/Gb. This indicates a very high safety level (intrinsic safety plus flameproof), suitable for hazardous environments, though over-specified for general water conservancy projects.

• Interference Immunity:

  • Strong Penetration: The high-frequency, short-wavelength characteristic ensures stable performance in fog, water vapor, and even light dust.

  • Obstacle Rejection: Built-in intelligent echo processing software automatically filters out false echoes and locks onto the true level.

 Data & Communication

• Output Signal: Standard 4-20mA analog signal with integrated HART communication protocol. This allows connection to traditional PLCs or secondary instruments, as well as remote configuration and diagnosis via a HART communicator or converter.

 Certifications & Services

• Explosion-Proof Certification: The product explicitly lists its explosion-proof rating, indicating it has passed relevant national or international certifications.

• Customization Services: The manufacturer (Yunyi) offers OEM, ODM, and custom design services to adapt the transmitter for specific project needs (e.g., special flanges, cable lengths).

• Quality Positioning: The product emphasizes being “maintenance-free” with a low total cost of ownership. Its listed application cases (petrochemical, food, power) position it as a mid-to-high-end industrial-grade instrument.

• Application Versatility: Beyond hydrology and water resources, it is widely used in petrochemical, chemical, food, and power industries, indirectly proving its durability and reliability.
