Radar Level Sensor

Product Features

• High-Frequency Millimeter-Wave Radar (76-81 GHz) Achieves ±1 mm measurement accuracy for reliable 

water level monitoring. Shorter wavelength ensures better signal reflection on water surfaces.

• Non-Contact FMCW Technology No moving parts, minimal maintenance, and long service life. Ideal for 

clean water, wastewater, rivers, tanks, and wells.

• Narrow 6° Beam Angle Focused energy minimizes interference from pipes, ladders, or tank walls. Performs

 reliably in confined spaces like stilling wells or flumes.

• Adjustable Short Blind Zone Suitable for short-distance measurement scenarios. Offers flexible installation

 even in low-head or shallow water applications.

• Built-in Bluetooth 5.0 Wireless Commissioning Configure and monitor via mobile phone or laptop without

opening the housing. Safer and faster on-site setup, especially in hard-to-reach locations.

• IP68 High Protection Rating Fully submersible design. Housing options: PP or stainless steel for corrosion 

resistance and durability. Operating temperature: -30℃ to 70℃ for harsh outdoor environments.

• Multiple Output Options Supports 4-20 mA, HART, RS485, and Bluetooth. Easy integration with PLC, SCADA, 

or telemetry systems.

• Wide Application Range Hydrology: rivers, lakes, reservoirs. Urban drainage: underground wells, pipe networks. 

Industrial: process tanks, storage vessels. Municipal: water/wastewater treatment plants.

FAQs

1.Why should I choose 80GHz radar over traditional 26GHz or 6GHz radar?
The 80GHz radar has a much smaller beam angle (narrower signal). This means it can avoid hitting tank walls or internal 

structures like stirrers, heating coils, and ladders. It also offers much higher resolution, leading to 1mm accuracy compared

to the 5-10mm accuracy of lower-frequency models.

2.Canit be used in narrow or confined spaces?
Yes. The narrow 6° beam angle and adjustable short blind zone make it ideal for stilling wells, flumes, and small-diameter tanks.
3. Is wireless configuration supported?
Yes. The GLT744S has a built-in Bluetooth 5.0 module, allowing wireless setup and diagnostics via a mobile phone or computer.
4. What housing materials are available?
You can choose between PP (polypropylene) or stainless steel, depending on your environmental and corrosion resistance needs.
5. What output signals does it support?
It supports 4-20 mA, HART, RS485, and Bluetooth. Multiple output combinations are available (see ordering guide).
6.What is the operating temperature range?
The GLT744S operates reliably from -30℃ to 70℃, suitable for outdoor and extreme climate applications.
7.How is it installed?
It can be installed using thread (PP-G1.5 or stainless steel G2) or a bracket. Cable entry is PG9 with a standard 10 m cable.
8.What applications is this product best for?
It is ideal for hydrology (rivers, lakes, reservoirs), urban drainage networks, industrial water tanks, and municipal 

water/wastewater treatment plants.
