SLT-WSR201 60GHz Radar Level Meter

High-Precision Non-Contact Radar Level Measurement for Water, Wastewater and Industrial Applications

Product Introduction

The SLT-WSR201 60GHz Radar Level Meter is a high-performance, non-contact radar level transmitter engineered for accurate and reliable level measurement in demanding industrial and environmental applications. Utilizing advanced 60GHz Pulsed Coherent Radar (PCR) technology, the WSR201 delivers stable, high-resolution measurements with excellent resistance to environmental interference.

Designed for continuous operation, the sensor provides precise level monitoring in rivers, reservoirs, lakes, irrigation channels, wastewater facilities, open channels, storage tanks, and industrial process vessels. Unlike contact-based level sensors, the WSR201 measures without touching the medium, reducing maintenance requirements while improving long-term reliability.

Its narrow radar beam and high-frequency technology enable accurate measurements even in environments containing dust, fog, steam, rain, snow, or condensation. The instrument is also unaffected by changes in liquid density or dielectric properties, making it an excellent solution for water management, environmental monitoring, municipal infrastructure, and industrial automation.

With Bluetooth configuration, 4–20 mA analog output, RS485 Modbus RTU communication, and an IP68-rated enclosure, the WSR201 integrates easily into modern SCADA, PLC, DCS, and remote monitoring systems while providing dependable performance in harsh outdoor and industrial environments.

Why Choose the SLT-WSR201 60GHz Radar Level Meter?

Modern industrial facilities require dependable level measurement that minimizes maintenance while delivering consistent accuracy. The WSR201 combines advanced radar technology with robust industrial design to provide reliable performance in virtually any weather or operating condition.

Whether monitoring surface water levels, protecting infrastructure from flooding, controlling irrigation systems, or measuring storage tanks, the WSR201 provides fast, stable, and repeatable measurement without direct contact with the liquid.
