In modern industrial automation, accurate level measurement is crucial for production process control, safety monitoring, and cost management. Radar level gauges, with their superior technical characteristics, are becoming a significant driving force for innovation in industrial measurement.
Technical Principle: The Precise Art of Microwave Measurement
Radar level gauges utilize the time-domain reflectometry principle, emitting high-frequency electromagnetic waves through an antenna system. These microwave signals are reflected when they encounter the surface of the measured medium. The device accurately calculates the time difference between transmission and reception, using the formula "distance = (speed of light × time difference) / 2" to achieve precise level measurement.
