JWrada-31 Radar Level Meter
The JWrada-31 80GHz radar level meter features an integrated antenna, Bluetooth 5.0, and HART protocol. Ideal for pharmaceutical, food, energy, and hydrology industries, it ensures precise and maintenance-free liquid level measurement with advanced echo-learning technology for stable performance in complex environments.
The JWrada-31 Radar Level Meter features an integrated antenna design based on 80 GHz Frequency Modulated Continuous Wave (FMCW) technology, with a 36 mm antenna lens and a measuring range of up to 60 meters. It is suitable for liquid level measurement in non-explosion-proof areas.
The JWrada-31 Radar Level Meter comes standard with HART communication protocol and a built-in Bluetooth 5.0 module. Paired with the “Jiwei Smart Control” WeChat applet, it enables wireless on-site configuration and monitoring for convenient operation. Remote configuration and monitoring are also possible via cloud data networks. Equipped with proprietary echo-learning adaptive algorithms, it can self-learn to identify false echoes, separate multiple echoes, and dynamically track targets. It automatically adapts to changing conditions, maintaining high-quality, precise measurements even in complex environments, ensuring long-term stable and reliable operation. The product is easy to operate and maintenance-free, designed for liquid level measurement in non-explosion-proof zones.
JWrada-31 Radar Level Meter is widely used in liquid level measurement for pharmaceutical, food, energy, and hydrology applications.
The radar level meter emits a frequency-modulated continuous wave (FMCW) high-frequency (80 GHz) electromagnetic signal through its antenna, with the frequency increasing linearly over time. It receives the electromagnetic wave reflected from the material surface. The periodically transmitted FMCW signal mixes with the reflected echo to produce an intermediate frequency (IF) signal. By analyzing the frequency spectrum of this IF signal using a Fast Fourier Transform (FFT), the flight time of the signal (TDR) is indirectly measured. Combining this with the speed of light, the radar level meter calculates the distance between the antenna and the material surface, thereby accurately determining the level height.
