Clouds 4G High-Frequency Wireless Liquid Level Meter
Non-Contact Radar Level Transmitter with 4G Telemetry
Clouds 4G High-Frequency Wireless Liquid Level Meter combines 80GHz FMCW (Frequency Modulated Continuous Wave) radar technology with integrated 4G CAT-1/CAT-4 communication. Designed for remote monitoring of tanks, rivers, sumps, and industrial vessels, it eliminates the need for on-site wiring or separate RTUs. Data is transmitted directly to your cloud platform or SCADA system via cellular networks.
Description
Key Features
