The GWR-3000 is a guided wave radar level transmitter designed specifically for liquid applications. It uses time domain reflectometry (TDR) to continuously measure levels in tanks and standpipes. It is offered with either a cable or rod customized to the depth of the vessel. The GWR-3000 level sensor measures all types of liquids including those with steam, vapor, foam, condensation, or those prone to residual buildup. The sensor delivers precise and reliable readings for both level and interface measurements. It is easy to set up using a simple, timesaving BinDisc interface and is virtually maintenance free. Comprehensive diagnostics built into the sensor ensure maintenance-free operation and high reliability.
