LR74 LevelWave (24 GHz)  Free-Space Radar (FMCW) Transmitter

Liquid level measurement for challenging applications 


Designed for liquids in harsh environments such as tanks with agitators containing corrosives, in processes with fast-changing levels (≤60 m/min; 196.85 ft/min), in process tanks requiring high accuracy, this FMCW radar level transmitter has everything to solve
tricky situations and replaces obsolete radars in high-end applications.

• M12 cable connector option lowers labor costs with quick plug and play wiring
• Coupling housing system allows safe installation – install the antenna separately from the electronics
• Process safety with Metaglas® second sealing barrier for toxic and dangerous products
• Quick intuitive set-up with push buttons or PACTware™ DTM
• Compatible with WirelessHART Adapter WHA-ADP2
