This article explains what a millimeter-wave radar level gauge is.
A millimeter-wave radar level gauge is a radar device that operates in the millimeter-wave frequency band to measure the level—i.e., the height or depth—of liquid or solid materials. It leverages millimeter-wave technology, emitting and receiving millimeter-wave signals to determine the material level. Compared with conventional radar level gauges, millimeter-wave radar level gauges operate at higher frequencies, delivering superior measurement accuracy and resolution. They are widely used across diverse industrial sectors—including petrochemicals, food processing, and water treatment—to monitor changes in material levels within tanks, silos, and vessels, transmitting data to control systems for real-time monitoring and automated process control. Moreover, millimeter-wave radar level gauges exhibit robust reliability and stability even under harsh environmental conditions, making them well-suited to a wide range of complex industrial applications.
What are the differences between millimeter-wave radar level gauges and traditional radar level gauges?
The primary differences between millimeter-wave radar level gauges and conventional radar level gauges lie in their operating frequency bands and measurement accuracy. Millimeter-wave radar level gauges utilize the millimeter-wave band for measurement, whereas conventional radar level gauges operate in other bands, such as the microwave band. The millimeter-wave band offers higher frequencies, enabling superior measurement accuracy and resolution. In contrast, conventional radar level gauges may exhibit relatively lower measurement accuracy.
In addition, millimeter-wave radar level gauges can avoid certain issues that traditional radar level transmitters may encounter during measurement, such as signal attenuation and multipath interference as the signal propagates through the medium. Millimeter-wave signals experience minimal attenuation in the medium, enabling them to penetrate liquids or solid materials more effectively and deliver more accurate level measurements.
In summary, millimeter-wave radar level gauges offer superior measurement accuracy and resolution compared to conventional radar level gauges, while also mitigating certain issues that can arise with traditional models. However, the specific choice of radar level gauge should be evaluated and selected based on the particular application scenario and requirements.
Product Feature Overview
The radar level gauge product series comprises frequency-modulated continuous-wave (FMCW) radar devices operating at 76–81 GHz. These instruments offer a maximum measurement range of up to 15 meters, with a blind zone of less than 10 cm. Thanks to their higher operating frequency and wider bandwidth, they deliver superior measurement accuracy. The products feature a mounting‑bracket installation method and eliminate the need for on-site wiring, ensuring quick and straightforward setup.
The product has the following features:
• Millimeter-wave RF chips enable a more compact RF architecture, higher signal-to-noise ratio, and smaller blind spots.
•A 5 GHz operating bandwidth enables the product to achieve higher measurement resolution and accuracy.
• With a narrowest antenna beamwidth of 6°, the instrument is less susceptible to interference in the installation environment and is easier to install.
• Integrated lens design, compact in size.
• The display/control unit and the water level gauge feature a modular design and are customizable.
• Low-power operation with a lifespan exceeding 3 years.
• Supports Cat1 (4G) and LoRa/LoRaWAN wireless transmission.
