What's the difference between radar level meter and ultrasonic level meter? Which water level measurement is better?

Radar level meters and ultrasonic level meters are two mainstream non-contact level measurement technologies with significant differences in measurement principles, environmental adaptability, and performance characteristics.

• Measurement Principle: Radar uses electromagnetic waves (microwaves), while ultrasonic uses sound wave propagation
• Environmental Adaptability: Radar is immune to temperature, humidity, and dust; ultrasonic is affected by temperature, air currents, and vapor
• Measurement Accuracy: Radar offers higher precision up to ±1mm; ultrasonic typically achieves ±0.25% accuracy
• Penetration Capability: Radar can penetrate foam and vapor; ultrasonic cannot penetrate obstacles
• Application Scenarios: Radar suits harsh environments with high temperature and corrosive vapors; ultrasonic works well in clean, ambient conditions

For complex applications like river monitoring, wastewater treatment, and chemical tank measurement, radar level meters provide superior stability and reliability.
