Design & Functionality
The ARLM-70 radar level meter features a compact antenna design that protects the sensor from dust, vapors, and gases while maintaining high measurement stability. Its FMCW radar technology transmits continuous microwave signals toward the liquid surface and calculates the level based on the reflected signal.
Because the measurement process does not require contact with the medium, the device minimizes wear and eliminates contamination risks. This makes it highly suitable for industrial environments where liquids may produce vapors, fumes, or varying process conditions.
Total Crossed Beams
The radar sensor provides a focused signal transmission that improves echo detection from the liquid surface. This optimized signal behavior allows the instrument to perform accurate level measurements even in tanks with internal structures, agitation, or complex geometries.
Beam Pitch Options
The antenna configuration enables stable radar signal propagation across different tank sizes and installation conditions. This flexibility allows the ARLM-70 to adapt to both small and large storage tanks while maintaining reliable measurement accuracy.
Intrinsic Synchronism
Advanced signal processing ensures consistent measurement results by filtering false echoes and unwanted reflections. The integrated echo suppression functionality allows the system to ignore interference caused by tank walls, internal structures, or process turbulence.
Operational Advantages
Industrial facilities benefit from the ARLM-70 radar level meter through improved operational safety and process efficiency. Continuous monitoring helps prevent tank overflow, enhances inventory control, and enables real-time process automation.
With its robust industrial design, reliable radar sensing technology, and flexible integration capabilities, the ARLM-70 Amanda radar level sensor is an effective solution for accurate liquid level monitoring across a wide range of industrial applications including chemical plants, water treatment systems, food processing facilities, and manufacturing storage tanks.
