Non Contact Large Lens Radar Level Meter for Corrosive Media and High Pressure Vessels
YLRW80G-A Wireless Radar Level Gauge
Millimeter wave penetration * Fearless in extreme conditions * Industrial-grade wireless level monitoring flagship
Description
The wireless radar level gauge employs advanced 80GHz Frequency-Modulated Continuous Wave (FMCW) technology, integrated with industrial IoT connectivity (LoRaWAN/NB-IoT/5G), to deliver high-precision, non-contact continuous level measurement even in challenging conditions including dust, vapor, and foam. Its millimeter-wave penetration capability ensures reliable detection through interference layers, achieving measurement resolution as fine as ±1mm. This eliminates inaccuracies commonly associated with conventional instruments under complex process conditions. Featuring IP69K protection and an intrinsically safe design, the gauge offers a maintenance-free and robust monitoring solution for demanding industries such as chemical, energy, and metallurgy.
