YLR80G Series Radar Level Meter

The YLR80G series is a high-precision 76–81 GHz FMCW (Frequency Modulated Continuous Wave) radar level meter, also referred to as a millimeter-wave radar. Operating in a higher frequency band than traditional Ku-band radars, it offers superior performance in long-range imaging, multi-spectral sensing, and detection in challenging environments with strong smoke, dust, or steam. Its high resolution allows for precise positioning of smaller targets and ensures reliable measurements even under complex industrial conditions.

With a maximum measuring range of 120 meters and an accuracy of ±1 mm, the YLR80G supports both 4-wire and 2-wire configurations, making it suitable for a wide variety of liquid and solid level measurement applications.

Features & Advantages

High Frequency & Wide Bandwidth: 76–81 GHz with 5 GHz sweep bandwidth ensures high resolution and accuracy.

Narrow Beam Angle: ≤3° beam allows use in narrow spaces or guided-wave pipe applications.

Wide Application Range: Suitable for both small tanks (blind zone only 7.8 cm) and large storage tanks (up to 120 m).

Robust Communication: Supports MODBUS and HART protocols for easy integration.

Flexible Power Options: Compatible with 18–28 V DC or 220 V AC.

Durable Construction: IP67-rated housing available in aluminum or stainless steel.

Advanced Signal Processing: Enhanced echo algorithms ensure reliable performance in harsh conditions such as dust, steam, agitation, or heating rods.


Typical Applications

Narrow or Guided-Wave Installations: Small beam angle ideal for constrained spaces.

Large Storage Tanks: Capable of measuring levels up to 120 meters.

Small Tank Applications: Minimal blind zone enables accurate measurement close to the antenna.

High-Precision Requirements: Suitable for applications demanding ±1 mm accuracy.

Harsh Industrial Environments: Performs reliably in strong dust, steam, or tanks with agitators and heating elements.
