The Importance of Reliable Level Measurement in Industrial Processes

In chemical, petrochemical, food processing, and high-safety industrial sectors, accurate liquid level meter is a core part of process control. Level information not only guides operational decisions but also directly impacts equipment protection, production safety, process optimization, and economic performance.

Industrial challenges include:

High-temperature liquids and vapor environments with severe liquid surface fluctuations
Highly corrosive liquids (such as sulfuric acid, hydrochloric acid, hydrofluoric acid) that damage materials and seals
Foam, acid mist, and dust interference affecting measurement stability
High liquid level ranges (e.g., above 20 meters), requiring precise and linear sensor performance

Under these complex conditions, traditional float, ultrasonic, or differential pressure level instruments often underperform, requiring frequent maintenance, producing unstable readings, or risking equipment failure, increasing downtime and operational costs.

Authority Reference: According to NAMUR NE 43, traditional level instruments have limited long-term reliability in highly corrosive, high-temperature, or dusty environments (NAMUR, 2019).

Jiwei Automations Liquid Level Meter: Radar Level Transmitters – Technical Advantages

Shenzhen Jiwei Automations (Jiwei Automations) independently develops radar level transmitters using non-contact FMCW 80 GHz radar technology, providing high-precision, stable, and maintenance-free liquid level measurement solutions. Key technical advantages include:

1. Materials and Corrosion Resistance

Critical components use PFA lining and 316L stainless steel with PTFE or PFA protective layers
Resistant to strong acids, strong bases, and viscous liquids
Significantly extends service life and reduces maintenance frequency

Technical Reference: According to ASTM G31-72, 316L stainless steel with PFA lining demonstrates long-term corrosion resistance in strong acid environments (ASTM International, 2020).

2. High-Temperature Adaptability

Operating temperature range: -40°C to +220°C
Provides stable measurements even with rapid liquid surface fluctuations or in vapor-rich conditions
Suitable for demanding processes such as high-temperature evaporation/reboilers, polymerization reactors, distillation/extraction tanks, solvent storage, asphalt/heavy oil tanks, heat-transfer oil/melted salt loops, slurry thickening tanks, leaching tanks, tailings return ponds, fermentation tanks (strong foam), pulp black liquor tanks, wastewater adjustment/neutralization/aeration tanks, and KO drums (torch separation)
Maintains continuous, interference-resistant level measurement even in challenging conditions with strong foam, volatile solvents, vigorous agitation, or complex tank internals (agitators, ladders, baffles)

Technical Reference: IEC 60534-6-1 provides performance testing guidelines for high-temperature level measurement systems.

3. Foam and Interference Immunity with Non-Contact Measurement

FMCW or pulse radar penetrates foam, acid mist, and dust
No mechanical wear or clogging issues
Continuous, stable readings reduce maintenance requirements

Technical Reference: ISA White Paper (2020) highlights that FMCW radar significantly reduces liquid level measurement noise and improves control accuracy.

4. Intelligent Features

Supports HART, Modbus RTU, Profibus PA protocols
Built-in Bluetooth (v5.4) for wireless configuration and commissioning via mobile devices
Remote monitoring and intelligent diagnostics enable real-time level data acquisition and alarms

5. Safety and Standard Compliance

Full Ex explosion-proof certification for safe operation in hazardous areas
Complies with API 2350 overfill protection standards, reducing overflow risk
ISO 9001 quality management certification ensures reliable production and supply

International Level Instrument Brands Comparison
