Guided Wave Radar with Modbus RTU

Model: GWR-2000

BinMaster’s GWR-2000 utilizes time domain reflectometry (TDR) to continuously measure the distance, level, and volume of powders or solids in bins, tanks, and silos. This sensor features hazardous location approvals, a very small upper dead zone, and assures highly accurate level measurement in low dielectric materials down to 1.3. It has 4 -20 mA and Modbus RTU communication options, making it compatible with your HMI or PLC, as well as BinMaster's Binventory LAN-based software program or BinView cloud-based monitoring.

Measure Inventory Levels with Guided Wave Radar

Measure solids or liquids in storage silos and tanks using a guided wave radar level sensor. The level transmitter sends a signal down a cable and calculates inventory based upon the time-of-flight. The BinMaster GWR-3000 is optimized for liquid levels and interface measurement. The GWR-2000 measures bulk solids in silos up to 100 feet tall.
