Radar Level Meter

Measuring Principle

The radar level gauge transmits a frequency modulated continuous wave signal (76-81GHz) through the antenna, the frequency increases linearly, and is transmitted in space at the speed of light, and is reflected on the surface of the measured medium, and is received by the same antenna, and the frequency difference between the transmitted signal frequency and the received signal frequency is proportional to the measured distance. The frequency spectrum of the reflected echo is obtained by Fast Fourier Transform (FFT), and the distance of the target to be measured is calculated.

Key Advantages

• Transmit frequencies up to 76-81GHz enable a more compact RF architecture with a higher signal-to-noise ratio.
• The 5GHz operating bandwidth enables the product to have higher measurement resolution and measurement accuracy, and can be used at the metrology level.
• The narrowest 3° antenna beam angle has more concentrated energy, stronger anti-interference ability and higher reliability.
• The measurement blind area is smaller, and the measurement of small cans will also achieve better results.
• Shorter wavelengths provide better reflective properties for small particles and inclined media surfaces.
• Sensitive measurement, fast refresh speed, small antenna size, easy installation, rugged and maintenance-free.
• Non-contact measurement, no wear, no contamination, can measure liquid and solid media.
• The display with buttons makes it easy to set the parameters of the instrument.
