Product Overview

The ADDA-LE-62 Series 80GHz radar level meter is a high-frequency radar level measurement instrument. The product details describe millimeter-wave operation, a smaller beam angle, concentrated energy, stronger penetration, and intelligent echo tracking processing.

It is used for non-contact continuous level measurement of liquids, slurries, and granular materials. The product details state that it can be applied to metal and non-metal vessels, reactors, and solid silos.

Working Principle

The general principle of frequency modulated continuous wave radar level measurement: the radar emits electromagnetic waves from the tank top. After the waves are reflected by the medium and received by the radar, the frequency difference between the received signal and the transmitted signal is proportional to the distance from the medium surface.

Because the speed of light and the modulation slope are known, the frequency difference can be used to estimate the distance from the radar installation position to the material surface. The level height is then calculated by subtracting this empty distance from the known total tank height.

Key Features

• Millimeter-wave radar with accuracy up to +/-2mm and minimum blind zone of 0.1m.
• Smaller antenna size for more operating conditions.
• Multiple lens antennas, smaller emission angle, more concentrated energy, and stronger echo signal.
• Can operate under adhesion and condensation conditions according to the product details.
• Larger dynamic signal range for low dielectric constant media.
• Multiple measurement modes, with radar response time less than 1s in fast measurement mode.
