Technical Characteristics and Design
-
80 GHz High-Frequency Technology: The use of the 80 GHz band allows for a very narrow beam angle, which minimizes interference from tank walls or internal obstacles. This ensures a stable and reliable signal even in the narrowest installation spaces or tall, thin silos.
-
Bluetooth Connectivity: The FMR10B features built-in Bluetooth for wireless remote access. Using a smartphone or tablet, operators can perform commissioning, maintenance, and diagnostics from a safe distance (up to 25 meters). The connection is fully encrypted to ensure cybersecurity.
-
It’s Me-Function: To prevent errors when multiple devices are installed in close proximity, the “It’s me-function” allows the user to trigger a flashing LED on the specific sensor they are connected to via Bluetooth, ensuring positive device identification.
-
Simplified Commissioning: The device software includes guided setup sequences, or “wizards,” that walk the user through the installation process step-by-step. This reduces the need for specialized technical training and ensures the device is operational within minutes.
-
Compact and Durable Design: With a measuring range of up to 10 meters, the FMR10B is exceptionally compact. Its fully potted electronics and robust housing make it resilient against the environmental conditions found in outdoor water monitoring or dusty mineral stockpiles.
-
Clear Segmentation: As part of the basic line, the FMR10B is designed for easy selection. By stripping away complex features not required for standard tasks, it provides a high-performance radar solution at a price point comparable to traditional entry-level technologies.

Standard Applications
-
Water and Wastewater: Level monitoring in open basins, pump stations, and storm overflow tanks.
-
River Monitoring: Measuring water levels for flood warnings and environmental data collection.
-
Utility Storage: Level tracking in plastic or metal tanks for water, diluted chemicals, and additives.
-
Small Silos and Bunkers: Continuous measurement of powders or granular solids in light-duty industrial bins.
-
Stockpiles: Monitoring the height of sand, gravel, or mineral heaps in quarries and mining sites.
-
Through-Plastic Measurement: Because radar waves can penetrate plastic, the FMR10B can measure levels in IBCs or plastic tanks from the outside without a process opening.
