CAT1 Wireless Radar Level Meter

4G Direct Connectivity · Millimeter-Wave Precision Measurement — The Smart Solution for Remote Liquid Level Monitoring

The CAT1 Wireless Radar Level Gauge is an intelligent level measurement instrument integrating 26GHz high-frequency radar technology with 4G CAT1 communication capabilities. Utilizing the Frequency Modulated Continuous Wave (FMCW) principle, it achieves ±3mm measurement accuracy while communicating directly with cloud platforms via 4G networks without requiring gateway conversion. Featuring an IP67 protection rating and an extended battery life of up to 5 years, this device is specifically designed for distributed tank level monitoring scenarios lacking mains power supply yet requiring high-precision measurement. It serves as the ideal wireless upgrade solution for traditional wired radar level gauges.
