Design & Functionality
The ARLM-54 is designed for flexible installation in industrial tanks and vessels. The antenna radar sensor can be mounted using either a top or bottom threaded connection, allowing integration into various tank designs and process equipment.
The sensor uses FMCW radar signals to continuously transmit and receive microwave signals from the liquid surface. The system calculates the distance between the antenna and the liquid surface to determine the exact level inside the container.
Advanced digital signal processing helps eliminate false echoes caused by tank walls, internal structures, or agitators, ensuring stable readings in complex process environments.
Total Crossed Beams
The antenna radar system uses a focused microwave beam to detect the liquid surface with high accuracy. This targeted signal minimizes interference from surrounding structures and ensures consistent level measurement across various tank geometries.
Beam Pitch Options
The radar beam design allows the ARLM-54 to perform well in narrow tanks, storage vessels, and industrial process containers. The focused beam angle improves detection accuracy even when installed in tanks with internal fittings or irregular surfaces.
Intrinsic Synchronism
The radar transmitter and receiver operate with synchronized FMCW frequency modulation. This intrinsic synchronism improves signal clarity and enables accurate distance calculation even in environments with vapor, condensation, or fluctuating process conditions.
Operational Advantages
Industrial plants require level measurement systems that remain reliable under changing environmental conditions. The ARLM-54 radar level meter delivers dependable monitoring because the radar measurement principle is unaffected by temperature fluctuations, atmospheric pressure changes, or vapor layers above the liquid surface.
This makes the device ideal for demanding applications such as chemical storage tanks, water reservoirs, wastewater treatment systems, and industrial processing vessels. With its durable construction, precise radar sensing technology, and modern communication interface, the ARLM-54 provides a dependable solution for industrial liquid level monitoring and process automation.
