Functions

Highly accurate liquid level measurement – 80GHz mmWave radar technology allows achieving accuracy up to 1 cm, making this sensor suitable even for critical industrial processes.
Narrow radar beam – the 4.5° beam angle allows precise signal focusing, reducing the impact of reflections and ensuring stable measurement even in narrow tanks.
Large measurement range – the ability to measure liquid level from 0.3 to 60 meters makes the sensor suitable for both small tanks and large industrial storage facilities.
Industrial communication – the RS422 interface ensures reliable data transmission to PLC controllers, SCADA systems, industrial computers, and automation systems.
Low energy consumption – thanks to ultra-low power technology, the radar can operate for a long time with minimal energy consumption.

Applications

In industry: suitable for measuring levels in oil and fuel tanks, chemical industry containers, water reservoirs, fuel storage tanks, industrial liquid storage systems, wastewater systems, and large industrial reservoirs.

For engineers and automation specialists: the radar can be integrated into PLC control systems, SCADA monitoring systems, IoT monitoring solutions, and remote tank monitoring systems.

For electricians: convenient to install and connect to automation cabinets, tank control systems, industrial monitoring systems, signaling or security systems.

In infrastructure and energy sectors: suitable for fuel storage facilities, oil bases, energy facilities, water supply infrastructure, and industrial warehouses.
