WE-T161 is a series of radar level monitoring transmitters, including LoRa, 4G, NB, etc., and the power supply mode is battery power supply and 24V power supply. The radar level transmitter adopts millimeter-wave radar sensors to calculate the on-site liquid level in real time according to the installation height and the height of the radar antenna from the liquid level. It uses LoRa, 4G, NB and other communications to achieve long-distance communication, combined with Shidian Technology’s industrial edge computing gateway products, and uploads them to the Shidian Technology equipment management platform to realize real-time collection, analysis, calculation, storage and display of on-site liquid level physical quantities.
