SmartLine Guided Radar Level Meter (TDR)

SmartLine Guided Radar Level Meter (TDR)


The Honeywell SmartLine Guided Radar Level Meter is a TDR (Time Delay Reflectometry) Level Meter for measuring level, distance, interface, level and interface, volume and mass. This unit is well suited for measuring liquids as well as granular solids. A remote housing can be mounted up to 14.5 meters/47.6 feet from the probe. The SmartLine Guided Radar Level Meter has higher signal dynamics and a sharper pulse than conventional TDR devices and therefore better reproducibility and accuracy. The maximum measuring range of the SmartLine Guided Radar Level Meter is 35 meters/115 feet.
