GWR-3000 Guided Wave Radar

The GWR-3000 level sensor available from BinMaster is a guided wave radar developed exclusively for liquid applications. It employs time domain reflectometry (TDR) technology for the continuous measurement of levels in standpipes and tanks. It comes with a cable or rod tailored to the depth of the vessel.

The GWR-3000 has the ability to measure liquids of all types, such as those with vapor, steam, condensation, foam, or those exposed to residual buildup. The sensor offers reliable and accurate readings for both interface and level measurements.

The level sensor can be easily configured using a simple, time-saving BinDisc interface and is almost maintenance-free. Comprehensive diagnostics integrated into the sensor guarantee high reliability and maintenance-free operation.
