Supmea WSR300, WSR200, WSR550 Radar Level Transmitters
Product Overview
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.
Key Features
- Non-Contact FMCW Technology: Accurate measurement unaffected by medium density, dielectric constant, or site calibration needs.
- Long Detection Range: Up to 120m (WSR550), ideal for large tanks and silos.
- Low Beam Energy: Safe for human and environmental use, with narrow beam for complex geometries.
- Robust Performance: Operates in dusty, steamy, or inert gas environments without interference.
- Multiple Models: WSR300 for standard liquids (30m), WSR200 for extended range (100m), WSR550 for solids (120m).
- Two/Four-Wire Options: Flexible installation with 4-20 mA HART or RS485 outputs.
- Compact and Versatile: Fits metal/non-metal containers and pipelines.
- High Reliability: No moving parts, minimal maintenance, and long service life.

Frequently Asked Questions
What makes these radar transmitters non-contact?
They use FMCW technology to emit microwaves, measuring reflection time without physical contact with the medium.
How do they handle harsh conditions?
Low beam energy and high frequency ensure accuracy in dusty, steamy, or high-temperature environments.
What is the difference between the models?
WSR300 (60 GHz) for standard liquids (30m); WSR200 (80 GHz) for extended range (100m); WSR550 (76-81 GHz) for solids and harsh conditions (120m).
Are calibration or on-site adjustments needed?
No, they are unaffected by medium density or dielectric constant, requiring no site calibration.
What outputs support integration?
4-20 mA HART and RS485 for compatibility with PLCs and DCS systems.
