The Supmea WSR300, WSR200, and WSR550 Radar Level Transmitters are cutting-edge FMCW (Frequency Modulated Continuous Wave) solutions for non-contact, continuous level measurement of liquids in closed or open containers. Operating at high frequencies (WSR300: 60-64 GHz, WSR200: 80 GHz, WSR550: 76-81 GHz), these transmitters offer long detection distances, low beam energy, and immunity to process conditions like dust, vapor, and temperature fluctuations. The WSR300 is optimized for general liquid applications with a 30m range, the WSR200 extends to 100m for larger vessels, and the WSR550 reaches 120m with enhanced solid-handling capabilities. Certified for safety and reliability, they ensure precise inventory management and process control in chemical, oil and gas, and water treatment industries.

The Supmea WSR300, WSR200, and WSR550 Radar Level Transmitters are suited for non-contact level measurement in challenging industrial settings:
They use FMCW technology to emit microwaves, measuring reflection time without physical contact with the medium.
Low beam energy and high frequency ensure accuracy in dusty, steamy, or high-temperature environments.
WSR300 (60 GHz) for standard liquids (30m); WSR200 (80 GHz) for extended range (100m); WSR550 (76-81 GHz) for solids and harsh conditions (120m).
No, they are unaffected by medium density or dielectric constant, requiring no site calibration.
4-20 mA HART and RS485 for compatibility with PLCs and DCS systems.
